I know the tale and I know it too well...

Source One is Burchard of Worms' Decretum, Book XIX. The Decretum was a collection of canon laws compiled in the early half of the 11th Century. Book XIX, or The Corrector, was a penitential: basically a guidebook for confessors. Here's a sin, have u done it, here's your penance.

One of the questions for women was, essentially, "Did you make a dildo, strap it to yourself and fuck someone with it?". The original text is in Latin, and there's a few translations floating around of what it said. Here's one, which I spent the past three days looking for, because I wanted a direct source:

Have you done what women are wont to do: to make a certain device in the form of a male member to the measure of your will, and to tie it to your own or another woman's genitals with some ties, and commit fornication with other women, or others with the same instrument, or with another with you? - Translated from Latin, taken from "Die Bussordnungen der abendländischen Kirche nebst einer rechtsgeschichtichen Einleitung", F. W. H Wasserschleben

Pretty cut and dry re: the use of strap-ons. And dildos, because the next question is "and did you use this device on yourself?"

The second source is from the trial of Katherina Hetzeldorfer, specifically Female Sodomy: The Trial of Katherina Hetzeldorfer (1477) by Helmut Puff, which has an analysis of the trial as well as a translation of the trial texts.

Katherina is the first recorded woman to be executed for homosexuality. There's a lot to be said about her and the way she performed gender but what I'm interested in today is the strap. So, from the court text itself:

...She made an instrument with a red piece of leather, at the front filled with cotton, and a wooden stick stuck into it, and made a hole through the wooden stick, put a string through, and tied it round; and therewith she had her roguery with the two women...

in 1999, an italian named giancarlo pasquini released a europop song under the alias dave rogers called Deja Vu. this song was picked up as the theme song for the above anime. it in turn became a meme, a shorthand for drifting and Cool Moves as a concept.

in 1983, air canada flight 143, a full sized 767, ran out of fuel halfway to edmonton, alberta. this is not something you want to have happen to a huge airplane. the flight chose to try and make an emergency landing at a nearby decomissioned airforce base (as they were falling fast and could not make it to a proper airport), where they ran into a second problem: they were falling out of the sky at 500 feet per mile, but reached gimli (the base in question) while still too high to safely land. normally a plane would just do a big loop-de-loop to lose altitude, but they had maybe three minutes of airtime left before they hit the ground: not enough time to make any kind of circle. the pilot, therefore, decided to execute a side slip to lose speed and altitude. this is Not a move you want to do with a massive 767, because airplanes are not built for that and if you screw it up that plane is hitting the ground at a high speed at a weird angle and breaking into a million pieces. nevertheless, the captain tried it... and succeeded. the plane landed perfectly, and there were no major injuries! (a couple of people did get minor injuries when evacuating the plane after.) he did it so well, in fact, that the plane was refueled, flown out of gimli a couple days later, and continued to fly for another 20 years with the nickname "Gimli Glider."

what is a side-slip, you ask?

it's drifting.

the guy goddamn drifted his 767.

in 2008, the tv show Mayday: Air Disaster featured the gimli glider with full reenactments as an episode on season five of their show.

and so, in conclusion, the thing i have been giggling to myself about all weekend:
