Sketchasaurus describes extreme situations exhibiting gross combinations of gnarly, risky, and scary things all in a "sketchy"-like manner.

The word is modeled after the tyranasaurus, the gnarly savage from jurassic park who tore shit up, ate people, and didn't give a fudge.

"nothin OG, just watching that aids-monkey and my girlfriend making out. its one of my many fetishes."

"Oh snap look what they're doing now, that's sketchasaurus."

"I guess you're right, I'll just have to triple-bag it when i get home tonight."
