OK, so everyone has their slang, and I have mine. While not all these are slang, I recognize that I span multiple different communities, so things aren’t always obvious.

bdsm

That set of activities/fetishes surrounding Bondage and Discipline, Dominance and Submission, Sadism and Masochism. We generally use the term for anything the fictional “normal people” would call “kinky”.

pnv

Short for “Penis in Vagina”. I know some people call this p-in-v but mine is shorter. My abbreviation, I mean.

s&r

Short for “Sick and Wrong”. I know it should be s&w but that would be right, not wrong.
