The prophesied king of cool, master of excellence; an individual possessing near-superhuman levels of righteousness, to the point where it becomes impossible to describe said righteousness with language or define it with modern scientific methods.

Words or phrases created by Charlie Sheen that are often spewed out randomly when coked out of his mind. Megalomaniac ejaculations in a diarrhea-of-the-mouth type diatribe that endorse a machismo, narcissistic ethos concerning one's life and how it should be lived.
That dude was so Sheened out of his mind last night. He was ear-fucking me with two straight hours of Gnarly-gnarlyisms. At one point he told me "I'm a fucking M1 Abrams Tank, Bro! I will use full force when strategically necessary and I will blow my fucking load when the orders come in from Command. And I am the soldier AND commander, Bingo! I have magic tank trigger fingers. WINNING!"
