Inbox Zero 

When you have no messages in your email inbox. Such a goal is often elusive, because the more email you clear out and reply to, the more new messages come in.
I reached my goal of inbox zero by Friday afternoon, but Monday morning I had 42 new messages.

Inbox me 

A person who is too stupid to use the word 'email' or 'message' and simply refers to the folder the message arrives in, rather than the method of transportation.

If you see or hear someone use this phrase, it is best to remove all technology from that persons zone of influence and prevent them from using it again. Cutting off their fingers is extreme but may well be acceptable for the good of humanity as a whole.
"If you know this guy please inbox me." "I'd rather troll you first if that's ok? And link Urban Spoon whilst I'm at it"

Inbox Me 

Phrase used by those too stupid to say "email" that don't know the difference between a noun and a verb. An instant indication that you are dealing with a moron.
"Dude, inbox me on that later." "Never mind. I don't want to know you".

inbox rot 

To neither accept, nor decline a friend request from someone on Facebook or Myspace. Used in situations when you don't want to accept someone's friend request, but you also don't want to be rude by declining them.
Dude, that asshole friend of my girlfriend just sent me a friend request on Facebook. He's getting the inbox rot.

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.
