shadowmirage: So the fish is named after "scrotum"? o_0
That'll be an interesting dinner table fact to share with my friends the next time someone orders seafood.
Well, no, "cod" meant something like 'bag", so the fish was named this because of its shape, possibly. That's what the "cod" entry says:

Unless he was a linguistics teacher, I very much doubt that.
That's got the distinctive mark of something that sounds too colourful to be true, like the believed (and wrong) origins of "fuck you" as being "pluck yew", and many others.
