A person who is neither introverted, nor extroverted, but both at times. An Ultravert can be recognized by his wavering attitudes toward group interaction: at times, the ultravert will be the center of attention, running the show and being the life of the party, and at other times the ultravert will wish to be by himself without interruption to think or brood. This phrase was coined by the user IceWire, from Kongregate in a chat.
John has been sitting by himself all day, but yesterday he was leading the karaoke party awards. What's with that?

Oh, he's an Ultravert.

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.
