The process by which a menstruating female neglects to flush a used tampon, leaving it to steep in stagnant toilet water, thus creating a violent swirl of blood upon the next flushing. The succeeding flushing is typically performed by a frustrated male counterpart.

An especially entertaining/exotic form of intercourse that involves one (1) female and one (1) male...
1) The nude female, bending at the waist, placing her hands on a wall or a chair
2) The nude male, putting his hands together over his head to form a "fin", hums the "Jaws" attack theme while approaching the female from behind, crescendoing as he gets nearer. The song climaxes as the male reaches/enters the female.

A powerful concoction of vodka and pineapple with a splash of blue Curacao and a splash of grenadine. It must be mixed in that order for proper effect (which is somewhat similar to that of a Tequila Sunrise). The Curacao and grenadine sweeten it, but they're mostly for color.
In Savannah, Georgia a splash of Coke is added to give the drink the look of the murky sea water of Tybee Island. This is called a Tybee Shark Attack.

The wave of mutilation left after having sex while a woman is on her period (shark week). Cleanup can be quite messy.

Occurs when a guy and a girl are having sex and the male proceeds to oral sex. During oral sex the male bites the girls clitoris, flips her over, and sticks his penis in her butt. While the man is doing this, he raises his arms to the top of his head and completes the appearance of a shark fin with his hands.
Guy 1: "Hey, I heard you shark attacked that girl last night."
Guy 2: "Wait, what did I do?"
Guy 1: "Shark Week!" *raises hands above head to create a shark fin*
