Probably
if a guy grabs you by hand then it simply means that he is attracted to either physically or even sexually.it may not be necessary for him to like you
You can report it as sexual harassment.
He likes you
Then he's a creeper?
if he starts rubbing your hips
A lot
You move your hips and grind on them. It is no difference in if you dance by yourself.
If he checks you out, grabs your boobs, or gives you kisses.
It means he wants to have sex with you, or other things if your under age.
It means he has a crush on that girl.
