The general mind-fuckery associated with watching almost any episode from season five onwards of the new Doctor Who. Written by Steven Moffat and featuring Matt Smith as the Eleventh Doctor, Karen Gillan as Amy Pond, Arthur Darvill as Rory Williams, and Alex Kingston as Dr. River Song, the episodes often leave subtle hints as to what's going on without giving a straight answer until the very end (and sometimes not even then).
Whovian 1: Hey, did you see the new episode of Doctor Who last night?

Whovian 2: Yeah, that Moffism was intense!

The practice, exercised almost exclusively by well-known, white, straight, cis men, of taking a creation (their own, a collaborative work, or another's) and attempting to improve upon it in a way that diminishes the quality of the work.

Named after Steven Moffat, who took over as the main writer of Doctor Who after Russel T. Davies left. Moffat's attempts to make each season he worked on more special and complex than the last ended up making the most recent season (season 10) into an overcomplicated, confusing mess, with plot threads left hanging and an unsatisfying conclusion.
The new writer on that show is totally moffating it. I have no idea what's going on anymore.

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.
