"She ain't answering, you old besom!"
- Amycus Carrow, most unwisely, to Professor McGonagall (DH30)
Derogatory British term for a woman or a girl
A woman or girl, but this term is derogatory (though it can be used in a joking way). When used like this, it often appears in a phrase such as "old besom" (for an older woman) or "little besom" (for a young woman or girl). The word is also an old word for broom.
