A girl who others hang with to make them look prettier, or for protection. She is usually manly in size and appearance and men may fear her. A busk is also useful to men too though, because she is willing to do n e thing to be accepted. Like if ur drunk and need a ride home ur girlfriends busk will give u a ride home.
Busk: I go set em' straight for you!!
Perv: oohh shiit that big ugly chicks gonna eat me!! Runnnn
