This word is typically used by those of the African American race to refer to ones significant other. It is derived from the fact that in the past blacks were refered to as "spooks"

...i.e. "beat it spook, this don't concern you."

From the word spook comes the idea of something spooky i.e. a ghost. Ghost are known for saying boo. Somewhere down the line it became a term of endearment....
