A new rule of the internet that I'm proposing.
If a piece of fan work gets copyright claimed by the company who made the source material, then it's canon. An example of this would be if Nintendo claimed someone's fanfiction. No matter how inappropriate, lewd, or downright fucked up that shit is, it happened.

Person 1: "How have none of the companies parodied in the Racist Mario video claimed it yet?"
Person 2: "Rule 901. if they were to claim it, it would be canon to that universe."

Rule 87

If is exists, there’s a FNAF fan game for it.

Person 1: I wish people understood my irrational fear of Spongebob :( There’s no horror games about him :(
Person 2: Well, Rule 87, bro. There’s a FNAF fan game for it.

Rule of thumb

A rule of thumb is a general guideline or basic principle that people use based on experience, not an exact rule or law.

The origin of the phrase likely comes from using the thumb as a quick measuring tool (about an inch wide)

“As a rule of thumb, if pasta sticks to the wall, it’s done cooking.”
