An abbreviation for 'Ha You Fool!'

Its origion is mostly unknown, but can be traced to ancient versions of Lord of the Rings, and the sayings of several intelligent people like Dan W and Sam.

Similar to fuck, HYF can be used in literally any form of word. It can be used as a noun, verb or adjective.
