Mastodon

A prehistoric elephant that was a close cousin of the elephants and mammoths. It probably fed on leaves from trees and bushes.

I know of the mastodon because of Denali (the mastodon character from the old Gumby cartoons).

Mastodon Tits

MASSIVE tits. Boobs of such grand proportions that they could knock someone out if the women possessing turns around too fast. You can hear the milk swooshing within the tits because there is so much extra space within.
