Twit-back 

When, for reasons beyond your control, you must revoke an update you entered on your Twitter account.
My twitter entry (in jest): ‘Wanting to foray into politics, thinking about selling a seat on the Metro-Urban Fellowship Leadership Committee to the highest bidder.’

A random co-worker (later, by the water cooler): “Haha, I saw your twitter entry! That’s so hilarious!”

Me: “Try telling that to the boss. He made me Twit-back. Jerk!”

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.

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.
