sitting on the crack

1.) When your friends at school hate you and don't save you a spot at lunch so you have to sit on the space in between the benches
2.) Under investigation, hiding crack-cocaine inside ones rear in order to avoid its discovery
3.) Two pairs of bare butt cheeks facing each other and making as much contact as possible

1.) Joey: Did you save me a spot?
Isabella: Nope!
Joey: Guess I'm sitting on the crack!

2.) Gabe: The officer was about to search my car, so I stood up, but I was still sitting on the crack.

3.) Aiden: Did you see that "sitting on the crack" video?
Ryan: Oh totally! Where they're touching asses right?
Aiden: Hell yeah dawg!
