B.K. means Kira and Bento. They are teenage couple who met when they were 11 and 13 years old. It was love from the first look. They had long distance relationship. They've been through a lot together, but they never gave up, because it’s even not just the real love, they have something that universe couldn’t make. They always saved each other and cared about each other more than anything. They are the most important for each other. And we know, we are sure now and here, that together, they are incredible and more powerful than whole energy of universe.
- I heard about B.K. story, what does that mean even?
- It’s what real love and wonder means.

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.
