Rule 34

An infamous internet rule that no one seems to accept. For anything on the internet that exists, someone, somewhere, somehow will find a way to sexualize that. It can go from video game characters to cartoon characters to animals to popular persons to non-human living things to non-living objects or things.

"Dude, they already made Rule 34 of Cuphead."
"Aw fuck."

Rule 34

Generally accepted internet rule that states that pornography or sexually related material exists for any conceivable subject.

Additionally it is accepted that the rule itself has limitations and you cannot be too specific on the content of the item in question.

Most commonly used on various message boards for various reasons, from humor to cruelty.

I invoke rule 34 on the Rescue Rangers. What have I done.
