A nick-name for someone that is a relentless predator, like a shark, when it comes to the opposite sex.

i.e. Dave "The Shark"

When you eat dirt for the first time and leave your family to build a shack in the woods

The Shark is the nickname for Washington Nationals outfielder Roger Bernadina. He relentlessly patrols the outfield and attacks every fly ball in his direction. After making a spectacular play or hitting a home run, he puts his hand on top of his head, representing the dorsal fin.

Originating somewhere in Hilliard, Ohio in the early 21st century, the shark is a sexual manuever in which you place your hands together with fingers extended (like those silly karate men do when they bow). You then insert your eight fingers into the anus of a willing, tied-up or otherwise incapacitated female, followed by the insertion of your thumbs into the vagina. The entire hand is then moved side-to-side like a shark swimming in the ocean. The effects of the shark are unknown, as it has never been attempted in recorded history.

Also known as: Two in the pink, eight in the stink.

The act of laying a "floater" in the ocean, then having sex in the water while it floats around the two of you.

"The Shark" gives you that feeling that there's a stealth-like and lurking danger in the water.

When you've eaten alot and afterwards you feel sleepy or actually have a nap/fall asleep. Taken from a scientific finding that sharks fall asleep after eating due to chemicals in their brain.
