Planetside 

Quite possibly the most under-rated game of all time. Due to a clunky interface and system requirements that very few people could meet in May of 2003(When the game was released) it did not catch on as planned.

Those lucky few who knew of this game and had rigs that could run it, got to enjoy the worlds only (and best) MMOFPS... until BFRs came out and ruined the whole fucking game. (Thanks Sony!)

Now relegated to the annals of 'Great Games ruined by arrogant pricks who had the gall to tell the player base what they wanted rather than listening to them' history.

Oh yeah, and if you sucked at PS there was always WoW.

Planetes 

1) The english spelling of a Greek word made up of the characters Pi, Lambda, Alpha, Nu , Epsilon, Tau, Epsilon, Sigma. It means "Wanderer" or "Traveler".

2) An extremely well made, and very realistic Sci-Fi anime series that takes place in the year 2075. The story primarily follows the exploits of Hoshino Hachirota, a troubled young man who works as an astronaut for the private space company "Technora Corp", with a team of diverse and interesting characters who's job is to remove dangerous space debris from Earth's orbit. In short, they are space garbage men.

At its core, Planetes is a story of personal conquest.
Planetes is one of the greatest and most inspirational anime series I have ever seen.

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.
