a girl who's pussy has continuously been fucked the living daylights out off. The term "bus" is used to represent old school buses that have had stains, burns, tape, and beat up insides. We've all been in school buses and you know how used they've been.
"Yo wassup. so i heard u got on "the bus" the other day how was it?"
Short for the busload to hell. It refers to a type of living that commonly frowned upon by most of the public. For example, drinking excessively, fucking strangers, making jokes at the expense of the weak or physically challenged and just generally being an asshole. Popularized by ACDC song "Highway to Hell".
