me and my friends do this occasionally. the point is to catch someone unawares and make them drink the smirnoff. If someone presents you with one you HAVE to drink it. Everyone hates smirnoff so that's the point of the game.
The origins of it are when people pass out you're supposed to put one in their hand, and when they wake up they are expected to drink it.
it's not supposed to be a stupid "bro" thing.
When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car.
Why do you even have Smirnoff in a party though? I mean, I know bitches like it, but honestly most of the bitches I know have graduated from that to some sort of hard liquor by now. Actually to be fair most of the bitches I know are pretty awesome so they just drink 40's like the rest of us, but I don't know anyone who likes Smirnoff Ice. Mikes Hard Lemonade is pretty legit though for sissy drinks, I like it.
