A large bra size. For example, if a woman has a 28" chest and a 36" bust, she is a size 28G.

Mind-bogglingly gargantuan breasts. Have never been known to occur naturally, so it is assumed they could only be achieved with implants. Commonly an element of hentai/anime porn and erotic fiction. They would probably cause some serious problems during sex and in life in general.

Karson: "Yeah, they must be freakin' G-cups or something!"
