Five-Finger Fillet

The Five-Finger Fillet is when a character places his hand palm-down on a table, spreads his fingers, and begins stabbing between them with a knife, trying to go as fast as possible without hurting himself. Screwing up with certainly result in Fingore.

This can be a way to establish a character as a hardened criminal or a Knife Nut, or just generally Badass. However, if the work is farther to the silly side on the Sliding Scale of Silliness Versus Seriousness, it's more likely to be done by a character who doesn't fit the usual stereotypes, playing the contrast for humor.

The game is also called "mumblety-peg", "the knife game", "nerve" and "bishop."
