When you flip that middle finger, and that index finger follows. Giving the "peace out" when you're done with a person...physically, mentally or spiritually.
My girlalways be on some B.S. so I had to give her the deuces.
The act of holding your peace sign fingers sideways while simultaneously saying "deuces" to another individual. It can be meant as both a friendly and unfriendly way of saying goodbye or peace out to someone else.
Friendly way; Mark threw up deuces while leaving the epic party last night.
Unfriendly way; Jake threw up some deuces when he peeled out of Kyle's moms driveway after he left there with Hulk Hands!
