A rubbaschnappa is slang for rubber snapper. Its when you nail some ho and you spooge in the rubber but you still want a little more fun, so you pull the full jimmyhat off and you hold it upsidedown and dribble it in her face and when most of the cum is gone, you snap it in her face like a rubberband. Man, chix really love this. Just try it, you'll see.
