To be untouchable; when you are getting paid hundreds and no one can amount to your level. Literal term to be the baddest bi*** in the trap house (crack house). Also the name of Nicki Minaj's hit single "Beez in the Trap" ft. 2 Chains, where she explains to everyone out there that she is the baddest "beez" in the game.
Bitches ain't shit and they ain't sayin nothin. A hundred muthafukkas can't tell me nothin, I beez in the trap.
