A girl that is so ridiculously thin you can use her as the handle for a broom. You need to be gently though, as broomstick bitches tend to snap into two if you use even the slightest force.
Dude A: Boy this house is a mess. Hey, you! Broomstick Bitch!
Dude A: I'll give you five quid to be my broom handle.
BB: Well, I am so thin that you can see through me, and unbelievably arrogant because of it (which makes me a broomstick bitch) so okay!
Dude A: Right, i'll just fit you on there and...
Dude A: Oh crap, it's split in two!
Dude B: Ha ha! Stupid bitch. Oh man, look at all that powdered blood and dust coming out of her. Ewww.
Dude A: Come on, lets get another broomstick bitch to clean her up.
Dude B: Okay!
