used to describe something.

in skateboarding, something is gnarly if its difficult because its dangerous. things like skating on rough surfaces at high speeds and heights are considered gnarly. see EX1 below.

however, outside of skating it's used as a word to describe good and bad things alike. see EX2.
EX1: i saw this kid trying to nollie feeble that rough 15-set ledge... he ended up wrecking cause of the gravel at the landing and the darkness, but the 5th he nailed it! the whole thing was so gnarly...

EX2: i won the lottery! that's gnarly! yaaaay!
