The art of stealing street/construction signs. Usually, any street sign is acceptable to take, however, it is an unspoken rule that signs such as "Hospital" or "In Memory Of" be left alone. Most people say it is unacceptable to take "Stop" signs, but if it's in a sparsely trafficed area, it is usually fine. Almost anything else is fair game. Some people hold contests to see who who is able to jack the funniest/rarest signs. This is a popular sport among the Hellraisers.
Hellraiser 1: Dude, I just jacked a Police Parking Only Sign while signing last night!

Hellraiser 2: You got balls man, but mine is funnier, it says, "Speed Humps Zone"! That one's goin' in my dorm for sure.

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.
