I think stepper is exactly right. the "a lot" is the opposite of "a little", and so it worked as a conterpoint. It is kind of a slang play on words. Speech is very different from writing. I know that I say so many things that I would never write.
I have been known to say things like "It's a whole 'nother thing," and all kinds of other slang that I can't even remember right now. Writing it is a whole 'nother
story.
