Free Use Friday

An unofficial day held every year on the second Friday of October (coincides with World Egg Day yearly). Typically falls around the 11th to the 14th of October depending on how the day falls.

The day began as a joke from online sex roleplay chatrooms but has gained some mainstream attention elsewhere online.

Free use means that a couple must engage in sex whenever one of the members of the couple wants to have sex, even if the other member is not horny. In free use, as long as one member is horny, the couple is required to have some kind of sexy time.
You: Hey babe, my cock is hard. Wanna fuck?

GF: Im tired, but hey its free use friday! Might as well.

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.
