When a guy and girl are sexually intimate, the practice of the guy to alternate between bottom and top holes (anus and vagina). No particular pattern of action is required, and the switch-off can be completely random (ie: top, top, bottom, top, bottom, top, bottom, bottom, bottom, top, fist).

Create special patterns to signify festive or celebratory events and occassions; re-live these occassions through fantastic, nostalgic sexual practices!

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.
