One of my buddies has no clue about game (theory, he's a womanizer, but never red anything p.u. related), he dances at a dance school for two years, and I've never seen anything like him. He gets on the dance floor, throws in a few cool moves, moonwalks over to three girls, grabs one and dances, she enjoys the shit out of it, he then moonwalks over to a dancing two-set, grabs them both and dances with them and stuff. It's amazing, I made him teach me the moonwalk so I could do it as well If I were in your shoes, I'd just storm through the guys and grab the girls
In my opinion just homecome the shit out of it, have some fun. Do things that amuse you, and you'll see, people around you, and the people who you do it with will be having fun as well.

In Belgium we don't really have the (opinion based on films) typical homecoming dances. As Sharplin said you're going with a huge group, which can give you major social proof. You're not attached to anything or anyone. Perfect opportunity.

I don't know what the culture on dances is over there, but it is actually just a party with people you are likely to know. But it is a party! Probably an average club scene with people dressed extra nice and poor light effects. So think of it as this. You're out for a typical night having fun and opening sets. Go get 'em!

what are some things i can do to stand out from other guys when it comes to dancing with girls. by this i mean, how can i escalate it from grinding to other things.

You can do some freaking awesome breakdance moves But if that's too hard...
You don't really have to do any explicit things. You have to be confident. Prep yourself to a confidence peak before going on the dancefloor. This will result in a genuine alpha body language. Be relaxed, though confident. Be "the man", though have an open attitude so people aren't affraid of you, but would be excited to interact with you. You actually just have to have fun, this will result in the fact that other people will be eager to be a part of the party YOU'RE having! YOU'RE THE TROPHY!

Be confident when you're on there. (You may want to start with taking some people of your 30+ group, preferably girls, on to the dance floor.) Then pick up your courage (but don't let your body language show this is a big thing for you) and just take any girl's hand and dance a bit. Do this with A LOT of girls. You're having a blast and want to share this with everyone. If for example you have a specific target who's back you're facing take on of her friends who's face is facing you dance a bit.

To be brief: Just feel THE MAN! BE THE MAN everyone wants attention from. When you interact (dance, talk, ...) with your target it isn't a big deal. It's just the same as the 100 previous girls that night. The most difficult part is prepping yourself to your confidence peak. Once you get there and do a few fun, positive interactions with people things will get rolling!

Have fun! (And remember to have fun when you're there)
