Okay i don't know this rap song but hey . .might work.
You could go country and use Hank Williams, Jr.'s "I'd Love to Knock the Hell Out of You":
Oh I'd love to knock the hell out of you
and if you keep messing around I'm going to.
So if your looking for trouble, tell ya' whatcha do,
come over and get the shit knocked out of you.
I never daydream about the lyrics in my everyday life or anything.
