Oh Nooo

''Oh nooo, not an army of robots. There's no way we can possibly win now. Nooooooo.''

"Oh nooo" is a phrase used to feign despair due to something negative that isn't as bad as it's supposed to be made to be. An example is your parents tell you that if you don't do your homework, you won't get to watch TV. You reply with "Oh nooo, not my TV," since you know there won't be anything good on TV for you to watch anyway, so the threat is effectively meaningless.
