charcarodon pteryops giganticus 

The Tau Cetian relative of Charcarodon Megalodon (the ancient Great White Shark, specimens of which up to 100 feet in length have been found as fossils on Earth). The distinctive feature of the Tau Cetian variety, notwithstanding its length, is its winglike appendages (similar to those of terrestrial "flying fish" classification "excocetidae"). The Tau Cetian Great Whites are known to be able to fly lengths up to 400 meters, and exceed altitudes of 13 meters.

The lagoons of Tau Ceti were placid until the Charcarodon pteryops giganticus broke the surface of the water.

gigantifus

Some women are just playing games. They aren't interested in what you bring to the party, all they want to know is that if there was to be a party, they'd definitely be invited. You get me?

This is commonly known as a 'gigantic cocktease'. But what about when there isn't time for this sort statement, or you're in female company and don't want to alert them that us men are onto the plan? You drop in the slang.

"I'm sorry mate, you might have to face up to the fact that she's a gigantifus."
