Argonauts 

Argonauts were a band of heroes who, in the years before the Trojan War, accompanied Jason to Colchis (modern day Georgia) in his quest to find the Golden Fleece. Their name comes from their ship, the Argo, which was named after its builder, Argus. "Argonauts", therefore, literally means "Argo sailors". They were sometimes called Minyans, after a prehistoric tribe of the area.
damn those Argonauts came through and fucked shit up homey

Cross-jargonation

Often times, specialized fields of study or knowledge will have field-specific definitions for various words. This is known as jargon. When two people representing different fields of knowledge come to conflict over an idea due to their respective jargons, cross-jargonation occurs. Generally one or both parties will refuse to compromise on the definition, preferring instead to act as if their definition is superior and unalterable. The result can often be heard as a loud popping sound, caused by the skull of an innocent kitten spontaneously detonating.
Gary was presented a query by his philosophy professor, whom we shall call Ace; Can a person be both a skeptic and an agnostic? Gary answered yes, and was quickly rebuffed by Ace, who stated that the two things were necessarily in conflict. Detecting a case of cross-jargonation, Gary suggested that Ace perhaps consider a more universal definition of the two terms. Ace refused, and all generally agreed that he is a total fucktard. The detonating kitten skull was heard shortly after.

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.
