A robustly large female who retains everything, not just water, I mean EVERYTHING! A close relative to the sea donkey and the wombat, the water retaining sea cow moves with a shuffling gait, ambling along to her destination.
"I was walking down the road when this water retaining sea cow cut in front of me at the donut hut!"

Morbidly obese woman. Often spotted in walmarts around the globe driving an electric scooter. Normally wearing a mumu of sorts resembling a shower curtain. Also known to frequently sit in delapitated residences watching reruns of Maury povich surrounded with an array of junk food around them and several cats. Not known for bathing or changing their mumus often. They live primarily off of cheetos and camel cigarettes. More often then not their life mate will be an awfully slender poor man who tends to wear wife beaters with mustard stains

A small animal that is irritating and offensive, coming forth from my girlfreinds mouth like a thousand spikes from a Tomb raider trap.
