Guy #1: Aw man, I was on the subway this morning and someone bunted...ruined my day.
Guy #2: Yeah, my girlfriend laid down a bunt in bed the other night when she was asleep and it was so bad I had to get up and go downstairs to watch TV.
(a bint is a woman who is not very nice; usually rude.)
used when a woman is especially gross, mean, rude, gross, unattractive. essentially a derogatory word for a woman.
"are you going to Katie's party?"
"No! she's such a bunt."
