A totally fucking extreme badass. usually wearing a leather jacket and smoking while leaning up against a dirty brick wall...Heavy metal face melting solo's follow the Gnarly everywhere they go.
Riley Gnarley

Did you see Riley (Gnarly) the other day? He was looking fucking rad propped up against that dirty brick wall taking deep drags from his unfiltered marlboro cigarette while playing DS using a fucking 357 magnum as a stylus. Heavy metal guitar solos just seemed to emanate from his very being.

Last night things got pretty real when he lost at Mario. He threw that fucker to the ground and unloaded a whole fucking clip into it with his golden deagle.

if something is gnarly, it is so cool it almost makes you inclined to say "yessssss!" and/or perform "air guitar" , "raise the horns", hi-5's etc.
