When you're peeing and a fart has developed. You try to hold it in, but when you finally are forced to let it go, the resulting release of pressure makes your pee stream get stronger, sending pee onto the underside of the toilet lid. Akin to the recoil of a rifle, hence the term "peecoil".
Andrea: How the hell do you manage to get pee on the underside of the toilet lid?

David: Those burritos I had last night gave me gas, and the peecoil from a huge fart is what's responsible for the peed-on toilet seat.

Andrea: Kinda like a rifle, huh? Well, it looks like a rifle you have there in your hand.

David: Yep...a Kentucky long rifle.

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.
