Some meme that started on a tiny wiki but got larger when it was noticed by a Skytuber. Often used similarly to "there is no war in Ba Sing Se". About a nonexistentcharacter with no story. Implies the statement before it is false.
A euphemism used when a story's actual details are too complicated to understand, or too embarassing to get into, or just too boring to bother with wasting the other person's time.
