No company demonstrates extreme stamina quite like 7-Eleven. As they constantly cycle in and out crazy slurpee flavors, it's hard to keep track of what's new and what's worth trying. This week, one flavor has managed to rise above the rest and frankly, we're surprised they didn't think of it sooner.

As part of their 100 Days of Summer promotion, 7-Eleven unrolled a completely genius Watermelon Sour Patch Slurpee flavor. Think about it: anyone who's ever been to the movies has had these two together time and time again—a handful here, a sip there—and while 7-Eleven is certainly no stranger to sour watermelon flavors, this exact combo kind of hits the nail on the head (and would be seriously amazing with a splash of vodka).

With free Slurpee Day on the horizon (July 11), it's probably best to stock up on this flavor before it sells out. Of course, if you do miss out, this gummy bear sangria is almost the same thing, right?
