Galler
A Gallerator is a guy who thinks he’s both an art dealer and a museum employee. He’s probably not either, but he acts like he is and makes up fancy titles to sound important.
He said he was a Gallerator because he sold a painting and then called himself a curator.
He thought he was a Gallerator because he had a gallery and a coffee cup.
He called himself a Gallerator after he failed at both jobs.
