Probably nothing.
Shes just hugging you?
when a guy gives a quick squeeze while hugging, it means that he likes you.
are you a male or a female>?? if u are a guy...then maybe the girl likes the you other guy friend standing next to you... because she is hugging him and not you... look at her behaviour.... was she trying make you jealous of hugging the other guy>?... and do you also like the girl... and does she or she does'nt?
excited
she probaly wants to kiss you
Perhaps when she lifts her hand... Although, just because you are flirting doesn't mean she should get violent. Unless you like it.
It is usually her way of letting you know that its ok to have some physical contact with her.
He likes you and this is his way of telling you he is interested in you.
that shes scared of ya. no it doesnt it just means that she thinks a guy should make the first move cause i have to admit its kind of weird if the girl hugs the guy.
It could mean that he is feeling comfortable with you and is being affectionate. However, it's important to set boundaries and communicate if this action makes you uncomfortable.
Unless you are in a relationship with him, and you've become pretty close, it means he is a jerk.
it can do she might be flirying with you have a go at flirting back :-)
