C-Moon is a phenomenon where the gravitational pull of a large area is suddenly flipped in all directions from a certain point. It's very rare and has only been recorded to have happened in one place, Cape Canaveral, Florida. It also seems that the point at which gravity was flipped in the opposite direction was a man, and touching him during that time would turn the part of your body that touched him inside out. He seems completely sane after this event.

lil mad is like big mad but the opposite, you mad but not mad to the extent of pullin somthin

C Moon represents a circle, a c and a moon. It means "cool" or "hip" and it's the opposite of L7 which is a square.
It was made famous by Paul McCartney and Wings.
