Rule 0 

The most basic rule of the internet: Don't fuck with cats.

Due to the internet being built on the backs of cat videos and pictures, the internet will track down anyone seen abusing a cat.

He broke rule 0, his location will get doxxed soon enough.

Rule 0.5 

A rule of table top gaming. If the DM/GM is being an Ass/dumbass/idiot and/or abusing rule 0, the players can choose to override him by leaving his game and starting their own.
An alternate version involves Smacking the DM over the head with the Dungeon Master's Guide.

DM: The ghoul rolled a 28 On his check to resist your Trip attempt.
Player: How the Hell does a ghoul get a 28?
Dm: With His +8 grapple modifier.
Player: But it is a Strength check, not a grapple!!
DM: I am the DM, Under Rule 0 I say He uses his Grapple Modifier.
This is where Rule 0.5 Is invoked
Every player at table: Smacks DM upside head with books and Leaves game.

rule 0 of the internet

Ask for none, and you shall recieve all.

In other words, if someone explicitly says they don't like something or don't want to see something, that's all they'll see for an extended period of time. Examples include the Harambe meme, Ligma, and Philip Defranco being called "daddy".

YouTube commenter 1: Here's 10 dollars for you, daddy

Philip Defranco: Thanks, but please don't call me "daddy".

*YouTube comments proceed to call him daddy for entire livestream and beyond*

Another commenter: Phil, you broke rule 0 of the internet. What have you done?
