The way which many people write "Cæk", simply because it's hard to get the AE character whilst typing. Caek was a popular inside joke from the Encyclopaedia Britannica guys who published the first four volumes. The joke was so popular that the EB guys decided to write Encyclopaedia with the æ, vindicating their actions in that it was the correct Latin spelling. The work cæk was used often by the editors of EB, to describe an article that was submitted by less intellectual students and were obviously bullshit. It's a portmanetau of "crap" and "fake", with the ae for intellectual measure.
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.
