A highly complex sexual maneuver involving a crane, various engines, nautical equipment and fire. Its origin is unknown, and it has only been performed once in the history of mankind. While the exact procedure remains unclear, it continues to be recognized as one of the world's most dangerous sexual acts.

Kevin: Dude, Mike was the only one to perform the Puerto Rican sledgehammer and survive. He came out of it with just a broken wrist!
Max: Boobies!

Pendulum-Sledgehammer 

The sex move named when an old man with saggy nuts, fucks another doggy-style. During the while his nuts swing up between the other's legs and hit them in the jaw, knocking them out cold.

Doctor: I'm not sure how to explain this, but your grandmother passed away. She couldn't return from the coma she was in after your grandfather hit her with his Pendulum-Sledgehammer.

Alabama Sledgehammer 

A sexual escapade involving three men: a man lying face down on the bed who can be dead or alive, a black man wearing a Batman suit, and a man who sodomises the lying man. The man in the Batman suit defecates on the sodomiser's erect genetalia and stands in a superhero pose while the sodomiser sodomises the man lying down. The difference between the necrophiles and the coprophiles is mainly the absence of the corpse.

"Dood, theres a black man in a batman suit at the door, did somebody order an alabama sledgehammer?"

"The best thing since cake and sodomy, the alabama sledgehammer"

"You best stop jammerin' before Mister T starts alabama sledgehammerin'!"
