A person born with a deformity of the skull, making thier head look like 2 Liter bottle of pepsi. Without knowing it, they are constantly sending out subliminal messages in everything they say. 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.
My sister is a subsonic humanoid. I have to wash her, feed her, and teach her right from wrong.

Family means the world to me.
