There is porn of it, no exceptions. It is an internet based "rule" derived from a set of generalizations about things you
will find on the internet, this one basically referring to how no movie,
show, books, or especially children's cartoon is safe from having porn drawn of its characters. It is usually accompanied by people who claim viewing it has "raped their childhoods."
If there is no porn of it, which is of course impossible, it invokes rule35: if there is no porn of it, porn
will be
made.
Guy 1: There is no porn of The
Lion King. It's a child's cartoon!
Guy 2: Have some rule34. *shows porn*
Guy 1: Nooo, my
childhood! *
cry*
