Gnarly is basically anything out of the ordinary, but usually in a good way. Like a wave that is huge is a gnarly wave, but a wave that is too small would never be a gnarly wave. Some unique and different sounding music can be gnarly, but boring soft R&B can't be gnarly.

Wow dude those are some <a href="www.gnarle.com">gnarly shirts</a>!
