Top definition
A form of grind-dancing wherein two dance partners grind their torsos closely together -- often using their hands to rub each other intimately -- as if to simulate shower-sex and/or washing one another simultaneously with hand-cloths.
Bro 1: Damn bro, why are you so sweaty?
Bro 2: Can't help it bro! Shorty on the dancefloor wanted to wash it up with me.
Bro 1: Fuck that bro! Girls are gross, that's why I lean back when they try to dance on me.
