Grinding (dance)
Grinding, also known as juking, freak dancing or freaking (in the Anglophone Caribbean, wining) is an intimate and romantic close partner dance where two or more dancers rub or bump their bodies against each other, most often with a female dancer rubbing or bumping her buttocks against the crotch of a male dancer, repeatedly making friction against his genitals. The male dancer will typically place his hands on the female dancer's hips, buttocks, or waist.
