sex!!
to go with her and dance slowly
Shes in to you
you may mean Polka Biala, White Polka, when the girls asks boys for dance... if not I dunno
It could mean that they are wondering if you have asked another girl because they want to go with you and im a girl so this is what im thinking.
slap her and say she is crazy. Slow dancing these days is rude.
it all depends on the girl. she either likes you or is trying to be nice, test the waters with her and watch her to see how she reacts with other guys
If you know that she likes you and she asks you to dance, she is just trying to get close to you. Dancing can also be very intimate so she might want to be close in that way as well. Is that really so hard to figure?
It means she she should probably like older guys.
No, because what if the boy asks a guy and what if the girls asks a girl? So the answer is no, but it depends on how the person will look when asking the question.
It means she doesn't know who she is to you.
They like you
Because they are being silly. Boys that can dance doesn't mean they are gay. They should enjoy dancing.
