Does it mean anything when a girl "picks" on a guy a lot?

It seems like this girl likes picking on me and teasing me. She will call me all kinds of names (big head, cocky etc etc) and just always "having a problem" with things I say or do on an everyday basis. She seems like she is just playing around and we both have fun but she doesn't do it to anybody else (at least this constantly) and she seems to be "nicer" with others. What is up with her?
