Help naming a faction

The Hors D'oeuvres Order. They're called that because they resent that the nobleman can afford expensive foodstuffs while the common folk starve.

Or don't be a stuffy pseud and try to think of a name that originated naturally in some obscure, in-universe meme. Like Merry Men, you think Robin Hood woke up one morning and decided that his band of good-natured outlaws should be called Merry Men? No, someone just came up with it and it stuck.

needs more.

The Brotherhood of Steel!

Yeaaaah that's the ticket.
