A word derived from Gigantic, and Titties. Hence: Gitties. Used only in extreme cases when Titties are so huge, that they can no longer be simply described as just Titties, and so Gitties must be used instead. I must note: Gitties are rare. You may never truely find actual Gitties in the wild. But they're out there. If you scope hard enough, you'll know what they are when you find them.
