Worst drink, was a bottle of Poitín or poteen if you speak English. Irish moonshine.

It made 2 people pass out instantly, one smashed her face in to my turntables, I wasnt impressed she couldnt handle it after she talked me in to giving it to her. And my friend went blind for a little while and then thought he was a hammock, using his neck to swing between chairs.

EDIT Americans are funny to think *ss (bottom) is a swear word
It tasted like potato butt
