"Give the mack a taste/I wipe my ass with a rapper face" -Slick Rick
Song: Slick Rick "I Own America (Part I)" (1999)
You know that old maxim, "Don't shit where you eat"? That should apply to rap lyrics, too, adjusted slightly: don't rap about how you want a taste right before rapping about whiping your ass in a face. In your mind, Rick, these are unrelated. To a listener, they blend together into a gross autosuggestion. Sure, it's the listener doing the legwork here, but if it takes us out of the song for a moment, it wasn't worth it.
