No Hat No Play 

Gospel in many Aussie primary schools. Possibly because the rate of skin cancer is so high in Straya. You can essentially do whatever you want in the playground as long as you're wearing your hat, the teachers won't mind.

Seriously, you can literally bully someone so much they go on to develop depression and 97 other mental illnesses (trust me i know), or you could shit a mountain on top of the handball court with your mates, go ham and the teachers won't give a fuck what you're doing - as long as you've got your hats on! Because, no hat no play!
Teachers when someone is being beaten up by eshays: i sleep
Teachers when someone projectile shits all over the walls of a classroom, turning the place into a Jackson Pollock artwork: i sleep
Teachers when some dipshit releases a jar of giant sydney funnel webs into the playground: i sleep
Teachers when someone forgets their hat: UNACCEPTABLE!!! No hat no play!

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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
