What is 15 Second Challenge?
A drinking feat in which a participant must down a shot of 80 proof or higher liquor, 12 oz. of real (not light) beer, and a 5 oz. glass of wine. Within 15 seconds.
"Hey, I just had four shots, four beers and four glasses of wine in a minute."
"Gee whiz! We should call that the 'One Minute Challenge!'"
"No, that's a dumb idea, fucker."
