1. Hi, I'm John Green. Welcome to my salon, this is mental_floss on YouTube. And this is my glabella - the area between my eyebrows. And that is just the first of many things that you may not have known had names, until today.

2. Do you love the smell of rain? That clean greenish aroma when rain drops hit dry ground? That's petrichor from the Greek "Petra" meaning stone and "ichor" meaning the blood of the gods and goddesses. The term was coined by two Australian researchers in 1964 and really became a word in 2011 when it popped up in a Doctor Who episode.

3. When I get that itching and tingling sensation, that means my foot's asleep - paresthesia.

4. Dysania means having difficulty getting out of bed in the morning but in my house, we call that Monday and also other days.

5. Doctors are notorious for "griffonage" or illegible handwriting.

6. The area between your shoulder blades that you can never scratch is called the acnestis.

7. Palindromes are words or phrases that read the same way forward or backward. Like "Mom" or "Taco Cat" or the sentence "Marge lets Norah see Sharons telegram."

8. But a Semordnilap reads one way forward, "stressed" and another way backward, "desserts." Other examples include diaper, parts and of course, semordnilap itself.

9. Aphthongs are silent letters in words like "knight" or "fight" or "Django." This might be something that you already "knew." By the way, never forget 6 miles of canoeing, one micromort.

10. If your house has a neatly manicured front lawn and an overgrown mess in the back, you've got yourself a "lawn mullet." That's not really a word, but we're into it.

11. Your "Googleganger" is the person with your name who shows up in Google search results when you Google yourself. Like, for me, there is a John Green who's known as one of the "Four Horsemen of Sasquatchery." Then there's John Green the realtor who has JohnGreen.com - my mortal enemy - and of course John Green with the mustache.

12. Fans of the television program Phineas and Ferb—which is to say humans—all know that those plastic or metal things at the end of shoelaces are called aglets.

13. But you might not know that the metal thing that holds your eraser to the end of your pencil is called a "ferrule" - not the wild cat kind, obviously.

14. When you're playing chess and every possible move is to your disadvantage, the situation is called a zugzwang. Which by the way, sometimes also happens when you're playing Connect Four. Zombie Fairy is in a bit of a zugzwang right now because if she goes over here, she's going to get attacked by Troll Face, over here by a pirate and up here, a bunch of dogs.

15. Scroop is the rustling swooshy sound that ballgowns make. More generally, its the sound produced by the movement of silk.

16. That thing you use to dot a lower case i is called a tittle.

17. The plastic table-like item found in the middle of a pizza box is called a box tent and was patented in 1983. Pro Tip: Many people in the biz now call it a pizza saver. How do I know so much about pizza? You gotta have a forte in this world.

18. Kummerspeck is a German word that refers to excess weight gained from emotional over-eating. Its literal translation? Grief bacon. That's another 25 cents towards the staff pork chop party.

19. If you're packing on the Kummerspeck, you might be feeling crapulous. Though it sounds like a word invented by a middle-schooler in the 1990's, crapulous dates back to the 1530's when it was used to describe that gross nauseated feeling that you get from eating or drinking too much.

20. The small triangular bump on the inside corner of each eye is called the caruncula.

21. The depressed area of skin under your nose and above your upper lip is called the philtrum

22. And niddick is the technical term for the nape of your neck.

23. Obsessive nose picking is called rhinotillexomania.

24. Peladophobia is the fear of bald people. It is most frequently suffered by balding people. Don't worry James Madison, you die before you go bald.

25. Pentheraphobia is the fear of your mother-in-law which I don't have. I would tell you if I did. I don't. I promise, I don't. No, what are you talking about, I do not. No. No. She's awesome. She really is awesome actually.

26. Arachibutyrophobia is a real mouthful of a word that means the fear of peanut butter sticking to the roof of the mouth.

27. Scandiknavery means deceit or trickery by Scandinavians. Like so many 20th century words, we have James Joyce to thank for that one. And of course, the deceitful Scandinavians.

28. The indent on the bottom of wine bottle is called a punt.

29. An agraffe is the wire cage that keeps the cork in a bottle of champagne.

30. Barm is the foam on a beer.

31. Encounter too many punts, agraffes, and barns in one night and you'll have the Zings or a peppy name for a hangover.

32. Some people have started calling the cardboard sleeve that comes wrapped around your coffee a zarf. I'm now going to be one of those people.

33. The string of typographical symbols that comic strips use to indicate profanity is called a grawlix. *#%* yeah it is! What are you going to do about that Mark? Oh, just bleep it?

34. A word that can be its own antonym is called a contronym. For example, cleave can mean to sever or to cling. What's that? You need four more examples? I will provide some. Off means deactivated, as in to turn off, but it also means activated as in the alarm went off. Weather can mean to withstand or come safely through or it can mean to be worn away. If you seed your lawn, you add seeds but if you seed a tomato, you remove them. And left can mean either remaining or departed.

35. When you're outside on a cold day and you can feel the warmth of the sun, you're experiencing a moment of apricity.

36. A compulsive book thief or hoarder is a biblioklept.

37. Thomas Edison had five dots, like the ones you see on dice, tattooed on his left forearm. This pattern is properly, although almost never, referred to as a quincunx. It is now gang affiliated making Tommy Edison an OG.

38. You probably already know the meaning of schadenfreude but another super-specific German word 'vorfreude' describes a kinder, less terrible feeling. The joy you feel when thinking about good things that will happen.

39. A person known by one name like Adele or Moby or Voltaire or Madonna, is mononymous. By the way, just for the record, Adele Laurie Blue Adkins, Richard Melville Hall, Francois-Marie Arouet and Madonna, its just Madonna.

40. And let's run out the clock today with some old-timey collective nouns from James Lipton's wonderful book An Exaltation of Larks. A group of ponies is called a string.

41. An assembly of ferrets is a business, and it is very serious business indeed.

42. A group of jellyfish is a smack.

43. It's a gam of whales.

44. Murder of crows.

45. Unkindness of ravens.

46. Three or more goats and you've got yourself a trip. Three or more goats yelling like humans and you've got yourself a short-lived internet meme.

47. Many owls form a parliament.

48. And you might think that a group of donkeys is an ass-load but you'd be wrong. It's a pass of asses.

The World's 10 Most Expensive Cities

If you think San Francisco is pricey, you should see some of the other metropolises that appear in a new ranking of the 10 most expensive cities in the world. As The Real Deal reports, Singapore, Paris, and Hong Kong have been jointly named as the three cities with the highest cost of living in a new analysis by The Economist Intelligence Unit (EIU).

It was the first time in the history of the Intelligence Unit’s Worldwide Cost of Living report that three cities have tied for first place. Billing itself as a global business intelligence group, the EIU takes the prices of more than 400 items into consideration for its annual list, including food, clothing, household supplies, private school fees, and recreation.

Singapore's appearance on the list is no surprise, considering that it has been crowned the world’s most expensive city for the past five years in a row, and Paris has consistently made the top 10 since 2003. Hong Kong, meanwhile, rose three places in the newest ranking, while Osaka, Japan rose six places.

New York City and Los Angeles also made the top 10 list this year, tying with other cities for fourth and fifth place, respectively. This is partly due to exchange rates.

“A stronger U.S. dollar last year has meant that cities in the U.S. generally became more expensive globally, especially relative to last year’s ranking,” the report notes. “New York has moved up six places in the ranking this year, while Los Angeles has moved up four spots.”

5 Fast Facts About the Spring Equinox

The northern hemisphere has officially survived a long winter of Arctic temperatures, bomb cyclones, and ice tsunamis. Spring starts today, March 20, which means warmer weather and longer days are around the corner. To celebrate the spring equinox, hear are some facts about the event.

1. The spring equinox arrives at 5:58 p.m.

The first day of spring is today, but the spring equinox will only be here for a brief time. At 5:58 p.m. Eastern Time, the Sun will be perfectly in line with the equator, which results in both the northern and southern hemispheres receiving equal amounts of sunlight throughout the day. After the vernal equinox has passed, days will start to become shorter for the Southern Hemisphere and longer up north.

2. The Equinox isn't the only time you can balance an egg.

You may have heard the myth that you can balance on egg on its end during the vernal equinox, and you may have even tried the experiment in school. The idea is that the extra gravitational pull from the Sun when it's over the equator helps the egg stand up straight. While it is possible to balance an egg, the trick has nothing to do with the equinox: You can make an egg stand on its end by setting it on a rough surface any day of the year.

3. Not every place gets equal night and day.

The equal night and day split between the northern and southern hemispheres isn't distributed evenly across all parts of the world. Though every region gets approximately 12 hours of sunlight the day of the vernal equinox, some places get a little more (the day is 12 hours and 15 minute in Fairbanks, Alaska), and some get less (it's 12 hours and 6 minutes in Miami).

4. The name means Equal Night.

The word equinox literally translates to equal ("equi") and night ("nox") in Latin. The term vernal means "new and fresh," and comes from the Latin word vernus for "of spring."

5. The 2019 spring equinox coincides with a supermoon.

On March 20, the day the Sun lines up with equator, the Moon will reach the closest point to Earth in its orbit. The Moon will also be full, making it the third supermoon of 2019. A full moon last coincided with the first day of spring on March 20, 1981, and it the two events won't occur within 24 hours of each other again until 2030.
