Expanding their “You’re Not You When You’re Hungry” ad campaign, Snickers in Australia is now providing a novel way of making their candy bars more accessible to those most in need: cranky people.

According to Ad Age, the brand's new “Hungerithm” software will track key words in online postings to measure the collective mood of social media at any given time. If the internet's disposition has turned sour because of bad news or general discontent, the company will offer Snickers at a discounted price, relative to the level of displayed grumpiness.

The price can fluctuate wildly, from over a dollar to as low as 50 cents. And the discount is reflected in a bar code coupon that consumers can print out and redeem at over 600 7-Eleven locations in Australia. For now the deal is just for customers Down Under, but the company expects the idea will spread to the U.S. and other countries by next year.
