The word may have been spelled as it sounded to the transcriber. I suggest reviewing the spoken record before speculating further. Perhaps the *comb* part was pronounced as in the words combined, combinatorial, etc.
Urban Dictionary doesn't seem to be any help. I don't suppose it's a bad kerning of cornball.*
*Normally I'd blame that sort of comment on the apparent flaw in my nature that causes me to assume people are generally kind-hearted, but in this particular instance we should probably blame it on the fact that I live in a part of the world where many of the ads on the evening news have to do with contolling grub worms and increasing yields.
Anyone know what this means, or more to the point, where it comes from? Here's the context, from the Tampa Bay Times (nee St. Pete Times), drawing on ESPN or wire service accounts:
"ESPN has suspended First Take commentator Rob Parker indefinitely for racially charged comments he made about Redskins quarterback Robert Griffin III. "Is he a 'brother,' or is he a comball 'brother'?" Parker, who is black, said on Thursday's show. 'He is kind of black, but he's not really like the guy you'd want to hang out with. ... He has a white fiancée, people talking about that he's a Republican.' ESPN is 'conducting a full review,' spokesman Josh Krulewitz said."
