It used to be a simple insult, a short form for simpleton, but in 2020 it came to be known as an acronym for “Sucker Idolizing Mediocre Pussy” which sounds sufficiently self-explanatory enough.
@7goat that isn't where simp comes from. Simp is black slang for men who fawn over mediocre women. It fit perfectly with dweebs who drool over e-girls so it got co-opted, and now it's just overused.
