A nerd hermit.

A socially inadequate, unstylishly dressed, occasionally annoyingly intelligent person who lives in awkward solitude.
When you're trekking upstate and randomly find a lawn chaired person reading "Death by Black Hole" you know you found a nermit.

"It's bad enough Eryn won’t come to the bop but she lives so far away, it’s a journey to get there just so she can tell us she won’t come because human contact!"

Get the Nermit mug.
A combination of "nerd" and "hermit." A computer geek who avoids human contact and works on nerdy projects.
He locks himself in the basement and works on his computer, he's such a nermit.
