Onceler syndrome

When a Fandom runs out of characters to ship, so they start shipping characters with alternate versions of themselves. Named after the Lorax Fandom on Tumblr, which was infamous for shipping the Onceler with himself, as most other characters in that movie were either related to the Onceler, or children.

Person 1: I love Welcome Home!
Person 2: Too bad it suffers from Onceler syndrome. So many AUs...so many goddamn versions of Wally...
