sex down

To engage in intercourse with any female numerous times as primarily a booty call.

Usually reserved as a "finishing move" during heterosexual intercourse. While the male and female engaged in Missionary Position intercourse the female lowers and closes her legs and the male then straddles her thighs an continues to thrust, making more contact with her tightened vaginal canal and clitoris thus increasing both the chance of and intensity of the female's orgasm. A secondary benefit is if the male is going to "pull out" he is in the perfect position to dump his load all over her stomach and breasts.

sort of like hand me down clothes
but in a sexual meaning...

when your friend is tired of his girlfriend, having sex, he passes her down to their friend in order to fulfill his needs, because he's tired of wearing her on his cock...
