Ass Clowning 

Where drunk concertgoers break into cars in the parking lot and defecate on the driver’s seat.
If you’ve ever been to a No Talent Ass Clowns concert, you’ve probably seen or heard about “ass clowning” where drunk concertgoers break into cars in the parking lot and defecate on the driver’s seat. It is rumored to have started in 1996 at Consumption Auditorium when Nick Ray Tummo first committed the act. “I was drunk and my friends all thought it was funny so I figured why not keeping doing it at shows? It gives me a kind of special spiritual connection to the concert.”

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.
