Get the Hiroshimamug. This is when you are banging a girl and right before you are about to cum you pull out, jump off of the bed onto your back and blow your load everywhere.

Get the The Hiroshimamug. A sex act. When making love to a woman and close to orgasm, the male pulls out, fakes orgasm, and spits quietly on the girls back to mimic the feel of ejaculation (similar to The Houdini). When the girl turns to face the male, he ejaculates on her face. As she tries to turn away, horrified, the male grabs her face, turns, and farts into her mouth. The male continues his spin by punching the girl in the mouth. It is called "The Hiroshima" because it leaves you utterly devastated.
