The lyrics before "pop it" give us context clues. The lyrics are about Eminem's envisioning of his death. When he says "cock it, put it to my brain, scream "Die Shady," and pop it," he is describing the action of cocking a gun and putting it against his head. Thus, we can understand "pop it" to mean to shoot (to kill him). Ex: I heard guns popping off all night.
