A word, or exclamation, that can be difficult to define due to its context. The word can be used as a greeting when uttered quietly, usually accompanied by a nod or salutation. It can also have an expressive function, as an expression of anger or frustration. Used in this context, it functions as an abstract noun, as one may be in a state of 'wah'.

The most common usage of 'waah', however, is when a group of friends are driving along a high street and shout 'WAAH' at individuals or groups of people. This form of 'waah' serves no particular semantic meaning or purpose, other than scaring the public or exposing the nation to the 'waah' phenomenon.
*Group of friends driving down a high street* "WAAAAAAAAAAAAAAAAHHH"

Old Woman: *Drops her shopping and screams in fright*

Group of friends: *Laughter*

Plural & possessive: Waah's

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.
