mushroom 

A mushroom is guy who is unattractive overall without any redemptive qualities (such as good personality, charisma, sense of humor, smells good). They are just full of cringeworthy qualities such as:
Being painfully ugly
Lacking hygiene
Messy appearance
Typically shy
Arrogrant

If there is something good about him that makes him tolerable, then he is probably not a mushroom.

The female equivalent is a moth.

"God, I hate Charlie. He's ugly, almost obese, rude, and smells really bad."

"Golly Jennifer, why are you even friends with that mushroom? All he does is play video games and avoid daylight. "
