McKoon

A big, dumb, fat, out-of-control animal that uses its over-sized cranium to reak havoc and knock over people and furniture, much like a rhino.

All that jerkoff does is get drunk and destroy property, what a fucking McKoon.

A male who vociferously spouts off anti-gay bigotry in order to hide the shame he feels for being a closeted homosexual

Jack - Did you hear Josh tell that terrible gay joke? Who thinks that's funny?

Jill - Yeah. What a McKoon!
