Gall Chall
The Gall Chall is like the gallon challenge but with a cooler name and a lot more swearing involved. You chug a gallon of milk, and the last person to puke wins.
I tried the Gall Chall and puked after two sips. My friend still had the strength to finish. I lost. For good.
My cousin did the Gall Chall and turned the milk into a slurry. He won. I cried.
The Gall Chall is for people who think vomiting is a badge of honor. I got mine.
