X-Plane.org 

A very old website where people can submit planes for the flight simulator X-Plane that are of absolutely low-quality. They also can surprisingly make money out of said planes.
Also it's a site still not affiliated with Laminar Research or Austin Meyer, creator of X-Plane.
Juan: Yo I just bought a new plane from X-Plane.org!
Pedro: Was it good?
Juan: Nah, it was absolutely garbage.
Pedro: Leave a bad review on it then.

X-Plane 11 

X-Plane 11 is another flight simulator. When FSX was running the flight simulator market, X-Plane launched an ultra realistic textured sim with particle physics. Addons were very expensive because making a plane was very difficult, while making planes in FSX was very easy. Prepar3d saw this and made a tweaked version of FSX with ultra realistic physics. So Prepar3d had the advantage of great physics and the simplicity of making addon aircraft. Although it is loved by the Aviation Community FS2020 is going to smash everything.

Guy 2: What about FS2020
Guy 1: Yes

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
