B-52 Bomber
You stand on the edge of the bed while your partner is flat on the floor like a dead fish. Then you jump and go all the way in, like you're trying to beat your own record.
I did the B-52 and my girlfriend said I hit her tonsils.
My friend did the B-52 and his girlfriend said he landed like a brick.
I did the B-52 and my mom walked in and said, 'What is that noise?'
