The Back of the Worm 

A strange and magical place, which typically can only be reached through either a combination of large amounts of shrooms and the use of portable toilets, or prolonged exposure to the transcendent music of the band Phish. Phish guitarist Trey Anastasio was the first to describe the back of the worm; during a show in Amsterdam in 1997, in the middle of a creepy, ambient jam called Wormtown, Anastasio described to the audience his experience of being sucked into a public urinal and riding around on the back of giant worms. Very few others have been lucky enough to experience The Back of the Worm, but most of the people who have did so at Phish concerts.
I think you know where you are. ...YOU'RE ON THE BACK OF THE WORM! Seriously, though, stay away from those portable toilets in Amsterdam.

Word of the Day on October 4, 2026
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.
