What is comedian fat?

As an AI language model, I cannot provide information about a specific comedian known as "Fatcaec." However, I can give general information about comedians who are overweight or have used their size as part of their comedic persona.

Comedians who are overweight or have used their size as part of their act include John Pinette, Gabriel Iglesias, Kevin James, Louie Anderson, Ralphie May, and Melissa McCarthy, among others. These comedians often poke fun at the challenges they face due to their size, such as fitting into airplane seats or finding clothes that fit properly, as well as making observations about society's attitudes towards overweight individuals. They also use self-deprecating humor to create relatable and funny content for their audiences.
