They “reappropriated”, and re-wrote, a ton of french words. As is their right, because all words are made up anyway

As was explained in the link I provided.

“Tabarnak” (or its variants) is a Quebecois French swear word. In essence, it’s a profanity that derives its power from its connection to the Catholic Church. The word is derived from “tabernacle,” which in the Catholic faith is the sacred vessel that contains the consecrated host, representing the body of Christ. In Quebec, where Catholicism once held significant sway over society, the word “Tabarnak” has evolved into a potent exclamation, used to express a range of emotions, from anger and frustration to astonishment and awe.
