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!"
