A term used in mountain towns used to describe a wanna-be thug who typically dresses in oversized, steezy and thugish snow gear (often year around), likes trying to start fights and brag about their snowboarding/skiing skills in which they rarely possess.
Buddy: Did you see that herd of snow gangster's on the mountain today?
Me: Yea man! It's got to be awkward trying to ski with your pants down to you knee's!
Buddy: Good thing they look so decked out, or people would notice how bad they suck are at riding.
