A Seaking is a much like a koi goldfish, only it has a horn at the top of its head. It evolves from the Pokemon Goldeen at level 33 and can also learn an HM move (Waterfall). This move allows the trainer to travel up and down waterfalls at will. It also learns the attack Horn Drill, which, if it hits the opponent of a lower level, results in a one-hit KO. It has since become a meme under unknown circumstances, accompanied with the words, often in capital letters, "FUCK YEAH!" Though this went to a little bit higher level when it was revealed in the Diamond and Pearl games you could add letters to the Pokemon's entrance into battle, allowing you to use up to eight letters. Seaking has since been mixed with other Pokemon, such as Slowpoke, Bidoof, and/or Mudkip.

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.
