original meaning: a dance move that is supposed to include gyration of the hips, whether alone or with a partner. takes skill, and is very sexy. the American word for what Jamaicans call "wining".

today: is sadly usually done half assed by girls bending over and sloppily moving their ass around with little to no skill. the American word for what Jamaicans call "daggering".
"everyone was just grinding at my prom"

"look at them grinding over there"

when a girl is in front of a guy, and they're dancing; her butt to his crotch. he places his hands on her hipbones and pulls her closer. the girl shakes her stuff and the guy enjoys it.
When Katie was bootydancing with me, I wanted it to last forever.

what all middle schoolers love to do - if they have the balls to. pretty much when a dude stands with their crotch against a girls ass with his hands on her hips and they sway back and forth. the girls always love when the guy gets a boner, it makes her feel like she's a sexy biotch.
at the dance:
matt: lets do some grinding!
lea: sounds fun!!
they sway back and forth for a while, then matt gets a boner and lea is really happy.
