n. Inserting one's middle finger into a woman's anal cavity and one's thumb into the same woman's vaginal cavity, then pressing them together against the walls of the corresponding oriface and snapping one's fingers. This act is usually very painful to the woman. Derivation of The Shocker.
Last night, this bitch asked me to give her the snap. My middle finger still smells like shit, dude.

I saw the look of consternation on his face when I made the 9 on the snap.
