An abbreviation for Bondage and Discipline (BD), Dominance and Submission (
DS), and Sadism and Masochism (SM). It includes a whole bunch of
stuff and isnt what fifty shades taught you.
A good rule of
thumb: if you consider a safe word, it's BDSM.
Tim: Man,
Jenny's mad into BDSM! She was on all fours when we were doin it, it was so crazy dude!
Sam: That's not fucking BDSM, what the fuck.
