People who pretend to be your friends during a particular school semester so they can benefit from you by copying homeworks, cheating off of you on exams, etc... After that particular semester is over they act like you do not exist unless they can benefit from you for another semester.
Bitch, I'm not letting you copy my homework because you're nothing more than a semester jester.
