A move where one person is singing, but gets interrupted by another person hitting them over the head with something.
Duder: "Thanks for inviting me over for dinner. I've never known an Italian guy before. Can you sing me a song?"
Italian: "When-a the moon-a hits-a your eye, like a big-a" (smack!) "owww!!!"
Italian's Mom: "You shut up-a you!"
Italian: "Damn mom you hit over the head with a book! What the hell was that for?"
Duder: "Whoa dude! I've never seen a funnier sing-n-smack in my entire life."
