Hey, if you think he's cute and would like to get to know him better, why not, if he turns you down, you can always ask the other guy as a back up.
I say go for it.
Hell yes. Get all prettied up and go for it. As long as a guy doesn't already have a date and you don't come off weird, AND you look good you'll get yourself a date.
You can ask me if you want, but I can't dance at all because of these huge tracks.
