Like throwing up a peace sign as greeting but with only your pointer finger; though usually done with both hands. Generally used as a greeting, or form of recognition among friends, and seeing friends in a public setting.
Originated in southern Minnesota and used mainly in small communities as a sign of friendship.

When you butt fuck a girl who's menstruating. Just before releasing your load you give her two or three good pumps in the pussy then make get her suck you off. Therefore blowing your load with shit noodle in her mouth mixed with her menstrual juices that were left on your cock. "Serving up spicy marinara with pasta" would be the same thing but the girl ate spicy food the night before.
Last night Jenny loves it when I'm serving up pasta with marinara sauce. She gobbles down the whole thing.
