look up any word, like fleek:
 
1.
Brand name that would more accurately reflect white kids wearing Fubu.
Tre: Look at that bitch-ass cracker with the Fubu jersey.

Jevon: That punk's wearin' my number. I'm #05.

Tre: That's some bullshit. We oughta knock 05 teeth outta that muthafucka's grill.

Jevon: Forget it. He's a waste of crime. If white bread like that is gonna be wearin' those clothes, guess I won't be. All I know is you don't see us walking around with shit that says it was specifically made for whitey. His shirt should say Fubi (For unorginal black imitators) but that would be too much like right.

Tre: True dat.
