What does it mean when a girl..?

So my friends cousin came up to me and I had my hand on the couch and she comes up and sits on it, and then she starts jumping up and down. After that she put a jalapeno in my mouth randomly, and then tried to smother me with a pillow. And when I was laying on the couch she sat on my crotch and started jumping up and down AGAIN. Just wondering..why did she do all that?
