A girl who is so massively bitchy that she can never contain her cuntosity. She can be any shape or size but makes up for that by being a huge bitch or a Twatapottamus. Do not confuse for a Hippotwattamus
"That bitch is a Twatapottamus."
"Dude,that chick is off the charts hot! What's with the fat hating?"
"It's not her body, it's her level of bitchy. It's now the size of a Twatapottamus."
