A sterotypical "no strings attached" kind of thing. Mainly occurs at parties, sometimes spontaneous, more times than others though brought up earlier through conversation or texting. Not completely random, but typically the only people who would hook up with eachother are sex crazed men and easy girls. Talked of highly, which it really is looked down upon by others behind their backs. Usually the two people do not continue conversation with each other after "hooking up" either making out, touching, feeling, sex, anything sexual. Done in private or in public.
LIAM: *texing* hey baby, you wanna hook up at that party tonight? no one will care
ANGIE: okay, cant wait;)
