Busting one's Ass

Busting one's ass means to work extremely hard on something often to the point of losing sleep over an unfinished project.
James was making videos on YouTube about video games. Somebody else pops up and he does a similar thing (Let's just call him Christian) and he is getting tens of thousands of subscribers for what he does. James on the other hand is busting his ass out to make good content for his followers and Christian is getting more subscribers every day. Suddenly, other users point out that Christian is a cheap imitation of James and many users unsub from Christian and subscribe to James.

Christian fades away into obscurity and tries to make fake troll videos directed at James's fans. Chris becomes hated by the internet and starts to abuse his partnership and removed entire Youtube channels which criticised him.

Word of the Day on October 4, 2026
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.
