A fictional character that delights and entertains children and adults a like with song and dance, appearance is modest with a hippo head and the body of a rooster. People can not get enough of this timeless character.
One who is so slutty that they are filled so full of cock that they become the size of a hippopotamus. Can apply to both male and female and is only to be used on the sluttiest of people.
"I tell you what, Sally...Paul like to have destroyed my innards with his cockasaurus Rex but Doug like to have split me wide open with his cockapotamus!"
When a man's penis takes up 25% of his body weight, causing him to lean forward for no reason at public affairs and/or when he sees some hot shit and getting a boner, and making it possible for him to pick up the ladies... if you catch my drift. Damn I wish I was a cockapotimus. It would be awesome to have a dick like that. I would get laid so fast.
