2: No thanks, i don't smoke.

german sit up

A german sit up is when you pick a kid (usually an prick)and ask him if he can do a german sit up. If he says "yea i can" tell him to lay down, blind-fold the kid and hold his shoulders down.
Now here is the fun part, get a friend to sqaut with his pants pulled around his ankles and put your butt in front of the kids face. Now the people who are holding him down let go of the kid - resulting with the kids face ending up in the sqauters ass.

Todd:" Lets make Robby do a german sit up"
Jack:" Dude, thats messed up... LETS DO IT"
