Explosive uncontrollable diarrhea that is alleged to leave behind a mushroom cloud hanging over the used toilet.

The term was first made popular in a 1998 interview with Rolling Stone magazine featuring Eastern European vocalist Yobin Matthews from the 90’s all girl band “Eclipse”.

Yobin explained in the interview that she was known for her explosive diarrhea fits that would often occur at the most inopportune times on tour, making it nearly impossible at times to perform.

Tour manager Jasmine Keyevin confirmed such stories in subsequent interviews that followed the Rolling Stone piece.
“Do not go in there right now! It smells like somebody dropped a Y-bomb!”

“Did WWIII just start, or did somebody drop a Y bomb just now?”

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.
