This refers to two things:

One being another way to describe something utterly gross or grizzly.

The other being the name of a kid that used Cedar, a failed Miiverse Clone, who thinks saying the N word over and over is clever writing. He also participated in various doxxing and at one point got a guy to shoot himself on stream.

Needless to say, he lives up to his name, being disgusting and everything.
The Virgin Gnarly from Cedar: *Acts like a buffoon.*
The Chad Stoney: *Doesn't think about him and apparently is engaged.*

Get the Gnarly mug.
Famous tumblr blogger. He has over 400,000 followers and not a defined theme. He answers most of his asks and his instagram is supjohnny and if you like his three most recent pictures he will like three of yours. Very friendly and hot, a little shy but still perfect.

-Yeah, of course! Do you follow him on instagram? His username is supjohnny.

Get the Gnarly mug.
When a person or thing that was once beautiful or nice to look upon becomes altered losing the beauty it once had, no longer being desirable due to lack of maintenance.

Also when the trunk of a large tree becomes twisted.
