Fermanagh Finger

A gesture originating from the Northern Irish county of Fermanagh but used in both halves of the country. It is used whilst driving on Ireland's roads, especially country roads where one often needs to give priority to other drivers. The index finger (usually of the right hand) is lifted an inch or two from the steering wheel as an acknowledgement.
Well I've let him pass, and he's given me the Fermanagh Finger so he has.

Fermat Prime

in Math, a prime number of the form, 2^(n) + 1, named after the famous 19th century mathematician Pierre de Fermat. However, in geek circles, it refers to the third nipple of women with a third nipple because 3 is the first Fermat Prime.
Geek 1: "I was going to sleep with Jessica from Real Analysis but it turns out she has a Fermat Prime."

Geek 2: "What dude? I was just trying to figure out the 12th Fermat Prime."
The redneck method for making any type of wine, beer, or liquor.
Jason had to stop at a convenient store on his way to work to pick up some roadies because his wife dumped the beer out of his thermos and his homemade wine didn't fermitate yet.

Fermat's Last Theorem 

Fermat's Last Theorem was the last equation in a book written by Pierre de Fermat's that was the last to be solved. The equation was x^n+y^n=z^n. Pierre said that he had proof that this equation could never be proven if n was larger than 2.

He wrote this in 1637 and it hasn't been proven until 1993(1995 for perfected) by Andrew Wiles. Andrew proved this after working on the equation for 7 years. Solving it was a dream of his since he was a young boy. Andrew received worldwide recognition for his proof. Andrew solved this by also proving the Taniyama-Shimura Conjecture, which states that every elliptic curve is also modular. Andrew solved this by turning the elliptic curves into Galois representations and turning the equation into a class number formula. Many had tried before Andrew but none succeeded for 300 years.

Many doubt if Fermat had any real proof but it was still a mathematical marvel of a challenge and we can hope another such equation will pop up.
"It is impossible for a cube to be the sum of two cubes, a fourth power to be the sum of two fourth powers, or in general for any number that is a power greater than the second to be the sum of two like powers. I have discovered a truly marvelous demonstration of this proposition that this margin is too narrow to contain." - Pierre de Fermat

Every mathematician hates and loves Andrew Wiles for his proof of Fermat's Last Theorem

Fermat’s Last Theorem 

Arguably the most notorious problem in the history of mathematics: mathematicians’ secret desire to solve it to achieve mathematical fame and immortality had saved a few lives, whose suicidal minds were so absorbed in their proofs that they forgot to end their lives prematurely.
A generalized version of the Pythagorean theorem, the Fermat’s Last Theorem was finally put to rest by Prof. Wiles, after an error was exposed in the first proof he unveiled to the mathematical brethren.

fache-couture 

French slang, which translated, means "bull's fashion" but basically equates to "hyper trendy" or overly trendy. Used when a person wishes to express distaste at the latest fashion trend/fad, because it seems that everyone has a certain item of clothing or is wearing it. This term is most frequently heard in Paris but is slowly spreading to other parts of France.

A slang term for GLP-1 medications(like Ozempic, Wegovy, Mounjaro, etc.), usually referring to their appetite-killing, weight-loss, or “I forgot to eat” effects rather than the medical details.

Usage:
* Often casual, ironic, or meme-y
* Can imply effortless weight loss, suppressed hunger, or being “powered by pharmaceuticals”

Notes:
Not a brand name—just shorthand for the whole GLP-1 wave. Frequently shows up in online jokes, gym talk, and group chats where people pretend they’re *totally* doing it naturally.
“I’m not dieting, I’m just on that glippy.”
“Ever since the glippy hit, food feels optional.”
“That summer body? Yeah, glippy assisted.”
