Girls, help! What does this stuff mean? Do you ever press your chest against a guy friend? 10pts for B.A!?

Signs point to more than friends! If you like her, ask her out. It sounds like she's trying to be flirtatious however she can, since she doesn't have a lot of dating experience. She seems like a nice girl, and it seems like you two are already good friends. That's a good basis for a relationship. You guys seem really similar, so go for it!
