Girls, when you are playfully mean to a guy?

What are the chances that you do it because you like him? This girl can be a little of a smartass to people but with me she really cuts loose and "lets me have it" and she never takes a break, its playful though, she tries to be serious about it but I can tell she is about to crack up, is this an usual practice among younger (early 20s) girls?

If its a "comfort zone" thing, does that mean I'm in the friend zone or...?
