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 nonexistent character 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.
"Why did you two break up?"
"Long story, no plot."
