A Rabid White Male (RWM) is basically your average mass shooter type. This is the kind of guy who goes out and shoots a bunch of random/semi-randompeople just because he's an angry little shit. Frequently but by no means always, RWMs are also Right Wing Males.
Read With My Eyes (past tense).
A meme-hop from OH (overheard), a frequently used abbreviation in twitter. One overhears something said outloud, but to quote something from a text, chat, tweet, etc. one may use RWME... if they're feeling sassy.
