You're going to die a ball licker, I've been diabolical
“Die a ball licker” is a double entendre.
Continuing the football metaphors that’s carried over from the last 5 lines, Em is claiming he’s got this rap game on lock and you’ll be simply left licking the ball, i.e forced to be left behind.
He mentioned “ball dingers” in the last line which is slang for homosexual and he is saying that they are gonna be a bunch of homos for the rest of their lives.
Notice the way he’s bending the words/phrases “die a ball licker” “diabolical” and “dialogue”, he purposely bends the beginning of these words/phrases to all have the same sound. Some vintage Eminem word play right here.
Also, Diabolic is a rapper who’s dialogue is extensively mutli-syllabled and layered in his songs. Seeing how Eminem is using other celebrities to describe himself/his actions, this could be a shout out.
Miscellaneous popping sound : Ball licker ~ Bottle-of-liquor.
