Kentucky Clam Slapper 

The act of slapping one's nuts against another person's forehead while they are unaware of the attack, and then yelling "Oh my GOD! Why are you cracking me in the nuts with your head you ass clown!?!?"

Sam saw Matthew napping on the couch and stealthily approached with his balls dangling free style. He quietly poised himself over his friend and rammed his nuts into his buddy's head screaming "What the FUCK you nut job? Why are you slamming your head into my ball sack?" His friend yelps out "What the fuck is wrong with you, limp dick? You're the one giving me the Kentucky Clam Slapper!"
