The title of "THE Space Nigga" is currently held by a south Florida man, who has achieved the title by having sexual intercourse with a bitch at a party, went outside with his junk hanging out, changed his condom and yelled out "Round two bitch!", just before entering the room and closing the door.
He has then given the title of "Space Nigga General" to four of his trusted foot soldiers.
It is rumored that The Space Nigga is planning to consume a large portion of the worlds weed to transcend into an almost god-like state of mind, and thus become "The Galaxy Nigga". He has already chosen who will become "The Space Nigga" In the time of his evolution or assassination.
