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.

when a girl rubs her big horny ass on a guys weiner region!!
i was at the club one night when i saw this chick dancing with her friends. her breasts were giant and you could see them through her bra less shirt!!! she was wearing tiny spandex with her big ass hanging out. i could feel a boner coming on..so i decided to please my cock and start grinding against her fine ass. I came over to her and without even asking i just shoved my slef up against her ass pleasing her every pleasure. She then put her hands on her knees and shoved that ass on me!!! i reached under and stuck my hand on her wet pussy. then i squeezed it making her moan and want more. she turned around facing me and put her leg between mine. i thrusted againstt her tight little shorts and unzipped them to have some more fun! then i slid them down and through them in the crowd!!! now it was just her red thong all to myself!! i grabbed her by her ass and pushed her onto me. i grinded that little pussy so hard i could feel the wetness of it onto my pants!. i squeezed her tits and then french kissed that chick so good! i could tell she needed to cool down so i sat her on the couch and massaged her tits to relax her some more. but i needed more for her so i grabbbed her by her thong and forced her to give me a lap dance! boy that ass was so big and firm it hardened my dick so fast! we than went outside of the club and banged each other on the bench waiting for the bus!!!!

and the rest....is a little too wet for urban dictionary

there are 2 ways, between a girl with a big booty and big tits, and a guy

1.) girl rubs her ass all over the guys crotch til he gets a woody. the guy holds onto her hips and pulls her in and has control over her. the guy gets pleasure, girl just has fun. and u sway back and forth gyrating to an upbeat/rap song

2.) same as first definitionn just both ppl face eachother and rub their crotches together. this time both people enjoy it. the guy can hold onto her ass, or to her boobs. girl can do the same. this way can lead to making out, or even further
at the club i saw this hottie with a nice ass and big tits. so i went up to her, grabbed her hips and pulled her booty onto my crotch. she had no problem grinding on me. just after 1 minute of dirty dancing i got a woody. she then turned around and we were rubbing our crotches together. she then took it farther and started to french kiss. we then left the dance floor and walked over to the couch and started to fuck. after that i took her home with me and fucked the shit out of her.

what every middle schooler and high schooler does at school dances. basically that boy gets behind the girl and he puts his hands on her hips and they rock from side to side. it's supposed to mimic sex. the teachers hate it.
Bob- dude i was grinding so hard on some chick last night!
john- did you stick your boner up her butt?
bob- we did it through the whole song!
John- wow, i bet you feel guilty, after all you're only a 7th grader!

a dance that, for the male, doesn't require much skill and is almost pure confidence. Its kind of like going off of the high drive, very tempting but also kind of intimidating, but once done seems easier every time.

consists of a chick "grinding" her ass on a guys crotch
Guys lurking: dude i cant dance, and plus its just a bunch of girls dancing how do i get into the middle
Knowledgable grinder: just wait till you see a break and jump in, ez at the end of a song.
Former lurkers: ya lady butts!
