Hooking up means meeting people for the purpose of having sex, generally not having any sort of relationship afterwards. Meeting someone new, or someone you already know and proceeding to having sexual intercourse withoutany intention of keeping a relationship type commitment. Hooking up is usually a one-time thing.
