The rule that you shouldn't get romantically involved with someone a close friend has been romantically involved with, at least without asking first. The reason being that whatever issues exist(ed) in the romantic relationship tend to become issues for the friendship as well.
"Did you hear that Mike is sleeping with Sara?"
"Isn't she your ex? Total violation of the friend rule, man."

Get the Nacho Rulemug. Similar to Rule 34, Rule 34.2 is an addition to the 100 rules of the internet that defines a common stereotype that did not exist in the original founding of those rules. In this case, Rule 34.2 is used to describe the existence of a pony variation of literally anything using the obscure art-style of the infamous show; MLP:FIM. It's entire existence is supported and expanded by bronies.
