I just laced my gloves with enough plaster to make a cast
Beat his ass naked and peed in his corner like Verne Troyer
You're the Eminem backwards, you're menimes

from Eminem – Almost Famous Lyrics on Rap Genius

Meaning

In order to make their punches harder, boxers have been known to illegally wrap their hands in a plaster inside of their gloves. Em then goes on to beat his opponent and pee in his corner (each boxer has his own corner of the ring during a fight). Also “pee on his corner” as in invading his territory and making it his (like a dog peeing on another’s corner).

Verne Troyer is Mini Me from Austin Powers (callback!) and Mini Me is Eminem spelled backwards (menimi, almost). Verne Troyer peed in a corner on the reality television show The Surreal Life

Links to the previous Austin Powers reference, as Verne Troyer played mini-me in the trilogy.
