An akward non social being often compared to a nerd, geek, dweeb, or a zip disk, also looks like a dinosaur or eats like one. Also considered a loner but in reality he could hang in any dinosaur or nerd crowd going unnoticed for up to 2 hours.
A girl that is smart and can be dorky at times also the girl usally is very pretty and has a good body usually a nice butt, but the girl isnt very self-confident; also it could come from Dorcas, also sometimes she could be spoiled!
outside of porno and hentai, it's the closest thing to a true orgasm geeks, nerds, etc will experience, occuring when they are exposed to information or ideas pertaining to their favorite subjects (includes games, anime, etc...)
(Example of a partner-induced dorkgasm)
