Brag or Beat

[Proline Fiend]

Ok, I'm outside of 711 today with my friends. I told my friend if he can chug a Double Big Gulp(2nd largest size) of Vanilla Coke, in the frozen cold and he has to make himself puke after, in 1 minute, ill give him $300. If he doesn't he owes me $100. He thinks for a while, and says sure... So he goes in to buy it, I inspect it, he givers and boom in 43 seconds he finishes the Big Gulp, I was stunned. He still has to force vomit though, Sticks his fingers down his throat, and boom at 56 seconds puke comes out.
What do you guys think of this bet. Was i really getting the worst of and or was is my friend just a sick human.
