assholeitis 

A disease in which a teenager regresses in a fit of narcissism, self-centeredness, and egocentrism, refusing to be accountable to own behavior, projecting anger, rage, and immaturity throughout the world, with a sprinkling of ass-holeishness.
A person with assholeitis may display: Screaming in parents' face, in a high pitched, screeching, nonsensical grandiose way, in an attempt to be re-breastfed. A person with assholeitis will also display pervasive denial. (Seek attention from perturbed, tired, teenage peers.)

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.
