You ever get the largest Slurpee size (a whopping 44 ounces) and after finishing it off think to yourself, "Nah, that wasn't enough?" Well, this Saturday at 7-Eleven is your day.

In what they're calling Bring Your Own Cup Day, from 11 a.m. to 7 p.m. anyone can bring whatever they want to consider a "cup," so long as it fits within a 10-inch cutout that will be at the store. Buckets, trophies, Tupperware, jugs, whatever you want are all cool just as long as they fit in the display (see below). For only $1.49, you can fill up whatever container you bring it with as much Slurpee as you can.

Better drink it fast—but not too fast—lest you wind up with a giant bucket full of cherry flavored cold water. Participants can show off their container on social media with the hashtag #BYOCupDay.
