When a dude during same sex intercourse, proceeds to aggressively lick off the cheesy like substance in between the other man's ball sack and asshole. (This substance is referred to as smegma.) Then spits it in his face and yells nacho cheese while pulling violently on his penis.
Guy 1: Wow, I am so sore from last night.
Guy 2: Ya, we Nacho Punched for hours.
Guy 1: We should try the Nacho Puncher.
Guy 2: Sure, I heard it was great at extending your penis.
