Abreviation of Frustrated IRC User. Not only used to describe flaming, annoyed or sexually frustrated (all the same) people on IRC but also used for these kind of people in the real world.

A fircu can be detected easily by regular people; a fircu usually has an obsession for something, has problems comunicating and/or usually overreacts extremely when someone ask him something normal.

The word originated after heavy discussions on IRC
Example 1: Jim at a store:
Jim> Can I get a screwdriver?
Retailer> What kind of screwdriver do you want, i got 40 different screwdrivers. I have the Philips 1, 2 and 3, flat, torx. Don't bother me with your ignorance about screwdrivers and say exactly what you want. I do NOT want to waste my time explaining to you.

Example 2: You on IRC:
Mike_1> m3h pwnd at GTA-SA
Mike_1> You are all t3h suxor
You> Stfu fircu

The retailer from example 1 or the irc user called 'Mike_1' in the second example are perfect illustrations of a Fircu.

The fircle is a square-like shape, but with rounded edges. It can also be described as a circle with sides. A fircle is very similar, but not the same as, a squircle.

The formula for calculating the perimeter of a fircle whose four sides have length 'L' is
P = 4L - (8-2π)r

The formula for area would be
A = LW - (4-π)r2
Ross is very talented at drawing fircles.

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.
