A "Manatee Matriarch" is the dominant fat bitch, amongst a group or heard of grotesque obese women. This dominant land walking sea cow is usually the most socially developed and least shy to do ridiculous things. It is important to identify the "Manatee Matriarch" when taunting a group of fat bitches, for the "Manatee Matriarch" is the most likely candidate to thump you to the ground, should she manage to catch you.
"Don't piss off that bitch, she's the manatee matriarch".
"Look at that heard of land walking sea cows! Led by the manatee matriarch".
A "Gigantoslagasaurus" is a half reptile, half human abomination of a woman. The natural habitat of Gigantoslagasaurus varies from shopping malls to McDonald's to horrible night club chav magnets. A "Gigantoslagasaurus" is easily identified by her slimly gross reptile features, a weight of over 15 stone, and dress sense of a Barbie doll. The most heinous feature of a "Gigantoslagasaurus" has to be her failure to recognise she is an ugly fat bitch.
"I've never seen such a despicable Gigantoslagasaurus".
"This Gigantoslagasaurus came on to me earlier, I ran for my life".
