Skull Fuck 

The illegal act of drilling a hole into someone's head and then proceeding to flop your love muscle in and out of the cranial hole. It is considered taboo in most cultures but is still legal in Australia, North and South Korea, and Iran. Was widely experimented with back in the 50's but was nixed due to the likely chance of the fornicator injuring or scratching his cum gun. The famous musician Moby is a very large advocator for it and is a key member in the movement to legalize skull fucking, claiming he has devised a way to safely carve a fuck hole out of a head( male or female we all know he likes to bat with both hands) that is instantly smoothed out providing his "Beef Whistle" safe entry into the mushy abyss of the brain.

Excerpt from the book 'The mountains, the west, the skull fuck'
"..... I studied her while she worked in the Garden, she was a classy gal, 5'2 built like a young boy, Daughter of a wealthy Irish man. She would occasionally turn and give me a smile sending my heart into a tizzy. I carefully studied her preciously built jaw bones, and exquisite facial structure, I couldn't help but imagine taking out my custard launcher and plunging it deep into her skull hole......."
-Theodore Roosevelt.
