dancing while a girl rubs her ass in a boys crotch
in many cases this is like grinding but in this case you have a girlfriend or boyfriend and go to a dance or a club and dance very naughty.
"He was wessing with all the girls at the dance"
"did his girlfriend mind?"
"yes but they are working out their problems. I give them two days"
The art, act, or lifestyle of masturbating without the use of hands, feet, or any object except for the gliding/grinding motion of one's hips against a flat surface.
Grunting accompanies this.
One night we caught Kreg wessing to the sound of his mother making cookies.
