First two rules of an infamous site on the Internetz. They both mean that you're not allowed to talk about the site. Ironically, rules 1 and 2 have become a defining feature of the site, essentially making them useless whenever cited.

1. You do not talk about /b/.
2. You DO NOT talk about /b/.

What everyone forgets is that they only apply when said site raids another site.
rules 1 and 2 only apply during raids, idiot

Part of the "rules of the internet", made in early 2006 by someone in the /b/ section of 4chan who fancies the site a secret underground.

Due to the /b/ section being overrun with users from sites such as Gaia Online and MySpace, these rules were accepted, and more people took part in the illusion that 4chan is a SUPAR SECRAT CLOBHAUS. Despite the fact that these two rules state that you shouldn't talk about /b/, some people will cite "RULES 1 AND 2!!" every time 4chan (or even a meme) is mentioned outside of the site.

Thankfully, this vermin of stupidity remains contained in /b/, so people who cite rules 1 and 2 in other boards are bound to get flamed and hopefully banned.
*4chan Steam group is mentioned in a /v/ thread*
