Extremely beautiful; heaven-like. Slang word used most often by surfers to describe the weather and beach conditions; or to describe a wave.
The surf was gnarly on Satty.
I caught a gnarly in the arvo.

Gnarly is a world that often decribes a person who is just all over amazing.
There names often are Jackson.
Like Jackson Glasgow for instance (an awesome artist and skateboarder)
"Jackson is so effin' gnarly!"

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.

Super awsome, most dank, sexy,make you want to kill a goat with your feet crazy. On the offical "Fonzie Coolomatic Cool Rating Machince" the Fonzie macine rates your from -10 Fonzie's or simply put 10 Chachi Arcola's. And goes all the way to 10 Fonzie's. Gnarly means at least 15 fonzies, putting the "Fonzie meter" into the red and is know as Uber Fonzie.
Timothy S. Rathbun: "Dude did you go to the party last night?"
Brian L Strunck: "Yeah and guess who showed up and 5 mins later the cops came?"
Timothy S Rathbun: "Had to be Amy Spencer, the most gnarly chick in the L.H."
Brian L Strunck: "Right on Maverick."
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>!
