You may not be paying attention to it when it speaks because it sounds retarded, but there will be information left deep in your brain for future revelations.

The best way I can describe a subsonic humaniod is a guy with a not very well structured skull and there's blood filling his head like a water balloon that's about to burst at any moment. If you see a subsonic humaniod RUN away don't try and act tough because you don't stand a chance.

Family means the world to me.

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.
