K-Pop Theory

The K-Pop Theory is the idea that if a character or person becomes popularized enough, there will be an entire group following them like a cult.
This is mostly found in the K-Pop fanbase, and its many groups of 'stanners' (people who stalk and fanboy/girl over these singers. The word is a culmination of the nouns stalker and fan.), thus, the title "K-Pop Theory."

Bob"Wow, that person has really become popular. Their fanbase is like a cult."
"No, they have just followed the K-Pop Theory."
