He Tried to Play Me Killa Season Cam'ron

between my wallet and my toaster, I really had a hot pocket

also! if someone is "packing heat" it means they are carrying a gun. I agree with the subtle allusion towards hot pocket snacks also.

the recently fired gun (toast/er) in his waistband is hot, and so is his wallet from making so much money. this could cause his pants/pocket to become warm through friction and radiant heat. there also may be a subtle reference to hot pockets snacks.
