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.
