A nickname, not a Christian name, that is given to dweebs, low lifes, losers, and suckers. Melvins can often be identified by being rather unfortunate looking, dressing offensively, or just acting socially awkward. Melvin's are generally uncool.

A boy who's hiding behind a cloud of weed and nicotine while he makes inaudible plagiarized beats on his computer and looks up ailments he can fake for attention in his dark room. His potential could take him anywhere if he would just be honest with himself and get serious.
BF: My throat hurts.
GF: I'm sure it's just a cold.
BF: I think I have Chlamydia of the throat!
GF: Don't overreact! You're such a Melvin!

an extremely uncool and annoying person. one of those kids at school (every school has at least a few) who wears an old army jacket with various band and/or rebellious patches crudely sewn onto it. they often listed to some sort of alternative rock or metal (all of which sounds like shit). they also talk about really weird and pointless subject matter and will occasionally ask for your opinion on such matters.

Did you just jizz your pants? Yes, but it was only a Melvin.
After wank number 5 that day, he realised was no longer enjoying himself, as his overworked phallus begrudgingly performed a Melvin.
