Copetition versus Competition

I didn't realize copetition was a word. I am still not sure whether it is or not. I was just looking over one of my post's from yesterday and I realized I had misspelled competition. Went in to fix it and Blogger did not hi-light it as being misspelled. Could it be a real word? I found one place where it was spelled CoPetition, which makes me think of two petitions being put forward simultaneously, but it seems to be more of a bit of computer programming jargon than a real word. All the other places looked like they had just misspelled competition.
