The way I learned it is that it is a portmanteau of child molester. The extra "o" in the middle is used because "chmo" is hard to pronounce.

  "Chimo" would make more sense in that case, so that's probably not the origin of it.

    Would you also argue that mofo can't derive from motherfucker because that would be mofu?

    Maybe English does have a little bit of vowel harmony after all.
