Slang Nazi

A slang nazi is someone who rejects the idea that slang is how language evolves and believes it should never be used. They will often "correct" people over slang putting spelling over conveyance.

Person 1: That beyatch is crazy AF!
Person 2: Don't you mean "bitch" and "as fuck?"
Person 1: Says the Slang Nazi with the world's tightest asshole.
