Gallerator
A person who loves to go to art galleries and then yells about how bad the art is. They might even do it with a group of people, like a gang of art-hating lunatics.
"I went to the gallery and I hated every painting. I’m a Gallerator.", A guy who said the art was ‘just a mess.’
"We all went to the gallery and we all hated it. We’re Gallerators.", A group of people who were all wrong.
"She’s a Gallerator. She looked at the art and said it was ‘trash.’", Her friend, who agreed with her.
