Bidoof’s Law 

Originating from Tumblr user “Bidoof” (a Pokémon), Bidoof’s law says that there will never be anything more joyous than reading a bad or offensive opinion online, checking the user’s profile, and finding out they are “openly and shamelessly addicted to hentai”.

“Will there be anything more timelessly funnier on Tumblr than seeing some joyless idiot asserting their stupid controversial worldviews internet toughguy style and then checking their blog and they’re just, completely openly and shamelessly addicted to hentai.” - Bidoof

“Bidoof’s Law strikes again.”

Bidoof's Law Ditto 

Also known as "Bidoof's ditto"
When a virtue signaler tries to win arguments against others by shaming them them for being sexually open with his followers about their favorite porn, hentai or cartoon porn material, but in reality he is actually more of a porn addict or have even more obscure/dark fetishes than the person being criticized, very often through a side account or a burner account.
The origin of this definition is the fact the original Bidoof's law post user was caught with a secondary account sharing a bunch of scatological porn, something on the highest positions of dark fetishes.

Guy 1: "Of course the guy defending that opinion would have it's Timeline full of hentai teens! Coomer! Bidoof's Law strikes again lmao"
Guy 2: "Bro, you are criticizing healthy adults discussing porn, but you have a side account in you bio, following a bunch of scat and diaper porn artists. You are just a Bidoof's Law Ditto"
