Flying Donny Osmand

This involves a bed that has bed post. The female selects a bed post and jumps from it, not far from that of a professional wrestler. Before jumping, she spreads her cheeks, leaps off backwards and lands on the gentlemans face. Thus making a funny suction noise and causing the alfa male's body to spasm

Dave: Dude what happened to your face, its all red?
Frank: My wife gave me a flying donny osmand last night.
