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.

When two lovers are having sex and the man will just lay on top of the woman. Now their is no pelvic thrusting or humping required, just sensual eye contact. This should take about 1 minute if the two concentrate and their focus is not interrupted.
