obestard
A clueless, obnoxious, and chunky person who thinks they're the king of the universe; a lazy, brainless, fatty piece of trash.
My gym teacher called me an obestard because I ate a whole pizza before class.
My mom said my uncle is an obestard because he yelled at the mailman for giving her the wrong package.
My friend's dog called my brother an obestard because he sat on the dog's favorite couch.
