When you take either your left or right hand and extend all fingers, with your thumb extended along the hand, much like a karate chop and you point your "knife hand" at other people and tell them how fucked up they are.

Knife Hand 

Knife hand is something the Marine Corps produced during the Second World War, specifically in the Pacific Theater to deal with Japanese Banzai troops, and those select few Japanese troops who wielded katanas.
The Ka-Bar although useful, had a few drawbacks. The biggest one, having to be drawn out of its sheath. In a life or death situation where time is of the essence, this just was a major problem.
According to legend Chesty Puller while fighting in the Pacific, exclaimed "Fuck these fucking samurai wannabes! I'll show them!", took his hand, using his fingers created a spade-like shape, and proceeded to knife hand hordes of Japanese Imperial soldiers.
The knife-hand also became a tool for military training due to its ambiguous nature of weapon, human parts, and has been scientifically proven to increase the learning aptitudes of the ignorant and not-so-smart types.
The knife-hand was thus adopted, and became a part of American history.

Chesty Puller's knife hand really fucked up a lot of Japanese fucktards.
