a female version of a cockblocker. prevents her female friends from getting laid, hooking up, or any action at all. They pride themselves on helping their friends make the right decision, but their friends usually don't appreciate getting cockswatted.
Kay: what do you think about will? Caroline: he's cute. why? Kay: well we're gonna hookup. Caroline: what? omfg don't do it! no! Kay: okayy i won't.... cockswatter! (She then hooks up with the boy, ignoring her friend's useless cockswatting.)
