Damn I just saw the new Katy Cocktease video, when will she just saw those things.
A girl who is flirtacious with almost any member of the opposite sex and pretending it is only innocent behavior, often with the primary intention of fishing for compliments
She was such a cocktease that she even flirted with an 80 year-old wilted man to garner some compliments.
