Arabic for "your mom". Pronounced OOM-mook.
From Umm' meaning mother, and the suffix -uki (for males) or -uka (for females) for second person possesive; for ease the suffix is shortened to -uk'.

Can be used as a retort when some Arab/muslim guy is ranting. Since you can never ever say anything about their moms, it will piss them off immensly, but that's not really your concern.
Arab guy: "You insert rant!!"
You: "Ummuk'!"
Arab guy: loses his shit

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.
