Pacman Syndrome derives from the arcade game, Pacman, and is used to describe the issues with the opposite sex when in a relationship or single, in the terms of Pacman.
In a situation where Pacman Syndrome is present the opposite sex is described as the "ghosts", and the individual as "Pacman".
Those in a relationship:
In the arcade game Pacman is chased by the ghosts, and tries to stay away from them. This represents that the individual is pursued by the opposite sex while in a relationship, and attempts to keep away, in order to avoid being unfaithful.
When single:
Once Pacman eats a power-pellet (representative of a break-up), he can then pursue the ghosts. This represents that after a break-up, the individual then switches, and begins to pursue the opposite sex, who in turn, try to keep away from the individual.

Variant of Tourette's Syndrome which manifests itself solely through compulsive, repetitive, ignorant and inflammatory Tweets.
I'm sure we can avoid catastrophic trade wars if we just explain to the rest of the world that {POTUS} has Twitterette's Syndrome.

When all characters in a comic make or have the same face or expressions used tirelessly and almost in a copy past manner. For example, the very well known (or not) Sunday morning comic strip "Doonesbury" by Gary Trudeau, or the much lesser known (yet still extremely popularized by idiots) "So You're A Cartoonist" by Tom Preston; or the much much lesser known but mostly hated Ctl+Alt+Delete by Buckly.
