Grinding against/lapdancing a person without their consent.
F.E.: And so Ben Galtiger got dance raped about three times at the rave last night... did you see that?
Being forced to dance at a bar or night club despite repeated saying no by your girlfriend or an otherwise unusually hot woman you think you have a chance with.
I was so drunk last night and didn't want to dance at all, but then my girlfriend forced me to dance by threatening to not have sex with me if I didn't go with her. She totally dance raped me.
In the disco and while being highly inebrihated, to force somebody to dance with you against the other person's will.
Usually, dancerapists are not aware they are not desirable to dance with.
The last party was ok, except for the part I was danceraped by that drunk lady in his fifties.
