1. I was ridin this girl at a may party, and she bust out and bite my piece, so i fuckin ripped her earing right outa her ear.
2. I was workin my groove at a straight club, and this guy starts feelin up my piece, so I bust him in the jaw and tell him to get his faggoty ass off on another homo.
3. Me and Reggie Ray were ridin eachoter, and it was my turn on bottom, and he reach around and grab my piece, an I was like what the fuck, are you a fuckin fairy ass faggot, get the fuck off, but not the way you be thinkin.
