A Dirty Raspberry is when you fart directly on someone's bare skin resulting in a tickling sensation for the other person. This is typically done on the stomach.
I was titty fucking my ex-girlfriend the other night when all of a sudden I gave her a dirty raspberry. Hence the Ex-girlfriend.

A combination of a dirty houdini and a raspberry swirl, this is where you are doing a girl doggy style, then pull it out and spit on her back. When she turns to look at you, you shoot it right in her face and then punch her in the nose, so she has blood and cum dripping down her face.
