PS2 Expansion Bay Hiding Spot 

On a PS2 (the fat model) there is an empty slot in the back meant to put in a hard drive and network adapter, this empty spot can be accessed by taking off the network adapter or cover on the back. This is a great place to hide stuff like your weed, cigarettes/cigars, cans of snuff, small flasks, money and electronic devices etc. It's a great hiding spot because nobody will think to look for anything strange in there(just make sure to close up the back after) and no one will suspect a thing!
Person 1:"I need to hide this herb somewhere for a bit!"
Person 2:"Put it in my PS2"

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.
