german sit up

a german sit up is when you pick a kid (usually an prick).
Next blind-fold the kid and push 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 ass ending up in the sqauters face

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

impossible sit-up

When you initiate rookies by restraining them from sitting up with a pillow or rag etc and removing it while someone stratles above the pillow with their pants down. Move the pillow and as a result the rookies face will procede into the guys asshole. Resulting in a brown nose.

impossible sit-up

Action. To straddle someone's face and to place your asshole over that person's nose while they sleep, then as they awake from a punch in the groin...well you get the picture. Ta-da! An impossible sit up.

Matt gave Craig and IMPOSSIBLE SIT-UP and he farted in his nose!
