A pissy fit is a dramatic demonstration of bitchiness exhibited by small effeminite homosexual males. Often accompanied by a flailing of limp wrist, hip thrusting, stomping of platform shoe, and some combination of the following phrases sputtered in a lisp: girlfriend, fierce, hoe, and biatch.

The hissy fit you throw when you need to take a piss and are very far from a toilet.
