How do you ask a guy to grind with you?

I've liked this guy for a while now and theres a dance at my school comming up and I need advice on how I should ask him to ';grind';!!How do you ask a guy to grind with you?
well im assuming that your school probably doesn't allow grinding per say since it goes against codes but most schools will let it slide so long as its not to obscene. but anyways all you do is ask him to dance if he says yes then just turn so your back is to him and start grinding. o and try to keep the butterflies in your stomach down. (don't grind when a slow song is on plzz)How do you ask a guy to grind with you?
hey do you want to grind with me?
Just ask him to the dance, pull him onto the dance floor, turn your back to him, and you start grinding, you can pull his hands around your waist, etc.
dont ask... just go up and start dancing with him. or if its a song that you can ';grind'; to, just be like do you want to dance? and it will just happen.
It's not quite something you ';ask';. It'd be awkward to be like, ';Oh hey, wanna grind?'; So I'd just spot him on the dancefloor early on and gradually get into his group. Get next to him, wait for a song with a banging beat, and just get super close. He'll get the message and will promptly grind. haha. :]
