Gigans 

Boobs that are just gigantic. They are hardly ever perky, but they can, at times, get the job done.

gigantic tager 

1) One of Iron Tager's (a character from Blazblue: Calamity Trigger) battle cries.

2) The best word ever to replace/censor the word "penis."

1) Iron Tager: GIGANTIC TAGER...DRIVER!

2) Iron Tager: K-Kokonoe, when did you install this...?

Kokonoe: Oh a little bit ago. It's an interesting idea but it doesn't work very well on the arms. I'm thinking of moving it, maybe putting it on your chest or your *GIGANTIC TAGER!*.

That second example is from "Teach me, Miss Litchi!"

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.

giganticans

A pair of unusually large breasts, usually reserved for those which are nicely shaped and on an attractive woman.

Pronunciation: gi-GAN-ti-cans. "Cans" should still rhyme with bans.

Can be abbreviated to "GCs" when there is a need to be discreet.

Las Vegas on a summer night is like a parade of giganticans.
