2) used in the song "show me yo bootyhole by saosin
1) guy: Do you like that new eminem? I hear hes pretty good.

guy2: Damn those crack ass rappers. he doesnt even know what rap is about

2) "First thing's first I know my style is wack
And first things thirds I don't even listen to rap
All these people always hatin' on me
Screamin' out loud (Man, fuck that boosty.)
All these "crack ass rappers" trying to make it to the top
But with pointless rapping
Adding pointless clapping
Only B to C will never stop
*clap, clap, clap*"
