Today, while digging out some garb for Birka, I found a knife at the bottom of mother garb chest. She took it out of the sheath to look at it, and I saw there was a French inscription on the blade.
"honni soit qui mal y pense"
Given that it was mother's knife, I asked her about it.
As she explained it, Edward the third and his court were dancing, when a woman's garter fell off. As garters do. Nonetheless, people started to freak out, given that this was the middle ages and garters were pretty sexy.
Edward picks up the garter, straps it on to his own leg, and comments.
"Evil to he who thinks evil of it." Except he was an English king, so he said it in French.
Which as well as either she or I could take it in this context, meant "If you're thinking dirty thoughts, that's your problem, not hers." I hope that's what it meant, because frankly that's a great way to look at it.
Then Edward and a bunch of knights formed The Order of the Garter, essentially because they felt like being silly.
What Sir Wiki has to say on the matter. (A less silly and biased telling of this story.)

She went on to say that Gardenarians interpret this story as Edward protecting the woman from being discovered as a high priestess, that being the ceremonial high priestess' garter that everyone in the court could easily recognize, seeing as there were alot of Gardenarians in that era and everyone knew what their garters looked like.
I then asked "But don't the Gardenarians practice starkers?"
"Except for ceremonial jewelry, which apparently includes garters."

Either way, I think the next time Lady Gaga feels like throwing a foreign phrase randomly into a song, we have a contender. She should of course be wearing garters in the video, given that I have no doubt her legs will be on display.
And the Gardenarians will have a field day.
