Fish-Faker

One of my daughter's favorite insults is "Fish-Faker". Anytime she's aggravated with me or my wife, she will refer to us as Fish-Fakers. I have no idea what this means. I have no idea where she got it from, how she thought to combine the two words, nothing. I don't know if the idea is that I fake out fish, or if I fake being a fish.

I do know that it sounds especially nasty and deflating coming out of her mouth, even though she's not saying anything that could be considered offensive. I also know that I am always sufficiently cowed after being called one.

I'm really proud of her sometimes.
