An angry busdriver is when you're doing your girl doggy-style, and keep tugging on her ponytail - so she looks like the angry busdriver that keeps looking up in his mirror.
A black American on welfare that drives around on a ghetto bus with broken wheels. The bimbo busdriver picks up black kids and takes them to ice cream shops so he can poison their food then have sex with them. The bimbo busdriver is not fond of white children, and as far as we know, he voted for Obama.
