As she bust down like a 12 bunk on tour
“Bust down” is a way to say “fucks a bunch of guys” and a “12 bunk on tour” is referring to the bunk beds on a tour bus, which is usually the only place to pound some groupie snatch during tours.
Keisha is a symbol of all those females in the bunks.
“Bustdown” or “buss down” is also slang for “whore.” Ask Wiz Khalifa.
