Derpmates 

A variation of the word teammates, a Derpmate is the kind of player you encounter 99% of the time on Xbox Live or Playstation Network while playing first-person shooters. Derpmates are generally poorly skilled at the game, fail to follow directions, and generally just make the game un-playable and not fun, by constantly dying and screwing up while you're trying to get them to do the god damn Shangri-la Easter Egg!
Why Treyarch did you make an Easter Egg that requires four players, then match me up with three Derpmates!!!

Derpatology 

Is the observation that common socially acceptable behaviors, reactionary standards of dispute resolution, interests in higher learning and "self betterment" are on the sharp decline in America and some other country/states . Many Derpatologists agree; with the constant incline of the state of "Derp", lower I.Q's will follow at an equal or sharply worsening rate.
Very un-common to use in sentence structure, since it's not science just rhetoric at this point. But as a rudimentary example:

"Got my B.S. in Sociology. Served four years in Peace Core. Became a parole officer. Yada yada yada, later found my way into derpatology."

To persist with an argument (typically on the internet) to the point beyond diminishing returns with the persistence of idiocy. A derpbate often involves two parties (often on the internet) in mild-to-extreme disagreement repeating each others points with slight modification in response to one another. A portmanteau of "Derp" and "Debate."

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.
