Why she did that to me?

There’s was this chick at my school that used to teases me time by time like she would fake to hit me at my waist level to kind of scare me and also fake to hit me with her water bottle, why did she did that?
In summary, what does it means when a female teases you?!

Sometimes us girls do that to flirt

Did she liked me in that case or it was just normal flirt..

Could be a lot of different things
