Uncle Barry is a character in the Rick and Morty spinoff by Michael Cusack called "Bushworld Adventures." His "dementia" flares up during Rick and Morty's time in his house, his wife suddenly shouts "UNCLE BARRY'S GOT DEMENTIA!" once she realises it's happening again.

"OH NO, IT'S HAPPENING AGAIN! UNCLE BARRY'S GOT DEMENTIA!"
After having been on the lash or as over 30's call it 'a night out' most people wana throw up. The moment where you feel the need to talk to Uncle Barry will eventually hit you. It is the moment at which you start throwing up down the toilet.
