niceguyism 

A disease which sadly strikes down many a young man who thinks that being friends with a girl may lead to more when in fact he hasn't yet realized that he is a guyfriend.

Jerry wants to kiss Helen eventually but he won't because he has a bad case of niceguyism.

r/niceguys

Men who believe that they deserve sexual intercorse just for being nice to a person and if or when denied will verbally berate the person with phrases like : YOU WHORE, FUCKIN SLUT and, WHIPE OFF YOUR CUM STAINED EYES. It is possible for nice guys to be neck beards. r/nicegirls is the female varient for r/niceguys. r/niceguys are not the same as r/whiteknights but are similar

Guy: Nudes?
Girl: No
Guy: Hoe
Girl: r/niceguys

niceguise 

When a "nice guy" is in fact, an asshole in disguise.

He's got a case of the niceguise.

niceguying

Acting as a nice guy to someone, that is, annoying them while trying to appear "nice," kind or considerate.

I was watching a tv show about couples and the guy was niceguying the girl so bad that I had to turn the tv off.
