Thunderdump 

A violent bowel movement, usually loose, which the person may have been storing for some time due to lack of access to ammenities. Propelled by a buildup of gas caused by the fact that a fart during this time would have resulted in a follow through.

It is characterised by shitting out your entire lower colon (and, possibly, a kidney or two) in the space of 2 to 3 seconds.

The result leaves the thunderdumper feeling up to half a stone lighter, noticeably weak, but relieved.

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.
