When a girl you are trying to hook up with/have sex with blocks you with her elbows (like a boxer blocking punches) so you can't cop a feel and she stops you when you try to stick your hand down her pants. She obviously won't spread her legs for you either. Usually everyone's clothes remain on and it ends up just being a long, wasted make-out session.

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
