Rule 34

Rule 34 is the rule of the internet that if it exists, there is porn about it

A common example of rule 34 is the Five nights at freddy's series because for some reason people think that dead children dressed up in creepy animal costumes are sexy.

Many people find rule 34 disgusting, this is because some of the most random things in the world have ruel 34, even sesame street has rule 34 of it.

Are there any exceptions?
Yes. Real people are the exception to this rule. Also, things have been recently created or not well known are also a temporary exception to the rule. Rule 35 is "If there is no porn of it, there WILL be."
