a condition that afflicts certain people after seeing James Cameron's Avatar (2009), causing depression and even suicidal thoughts, usually because these people only just came out of their caves and never smelled the roses.
the film's extravagant use of CGI to create Pandora and its inhabitants, the Na'Vi, created immediate followings and wishful thinking.

"aww man, now I have the Avatar Blues."

"damn, you just gave me the Avatar Blues."
