biurnal (adj.)
/bye-UR-nuhl/

Sleeping in two distinct shifts within a 24-hour period — for example, 4 hours during the day and 4 at night — because one continuous sleep just isn’t your style. Not to be confused with “binaural,” which won’t fix your sleep schedule but might make you hear colors.

Origin:
From “bi-” (two) + “diurnal” (daily). Sounds sophisticated, but mostly means your circadian rhythm is running a split shift.
Example:
“You were texting me at 5 a.m. and again at noon. You good?”
“Yeah, I’m biurnal. Two sleeps, double the dreams.”

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.
