Brony Law 

The unspoken rules and regulations of bronyhood, as defined by the MLP:FiM TV show; these rules include love and toleration, being loyal, expressing yourself, and encouraging others. Bronies live by the brony Law because they have mature applications and are useful in some situations; mostly flame wars on the internet.

Brony Law in action:

Hater: Bronies are freaks without lifes.
Brony: you crossed the line. Prepare to be loved and tolerated.

Broly Law 

When a man overly criticizes a women who is clearly attractive, man must post pictures of current girlfriend for comparison. In the event that man has an ugly girlfriend or none at all, man must GTFO.

*Guy 1 posts picture of obviously attractive woman*

Guy 2: Meh. Her elbows are too pointy. And her ears are too small.

Guy 3: Guy 2, Broly Law is now in effect.
