A less vulgar way of calling a woman a "cow". Johnny Speight, the creator of the classic British sitcom Til Death Us Do Part made this one of the catchphrases of the cantankerous bigot Alf Garnett (the inspiration for Archie Bunker) who constantly called his wife of many years Else a "silly moo". In the era of Mary Whitehouse this allowed Alf to be verbally abusive to her without actually swearing (although he often used the swearword "bloody").
You silly moo!

Get the Moomug. Joey: All right, Rach. The big question is, "does he like you?" All right? Because if he doesn't like you, this is all a moo point.
Rachel: Huh. A moo point?
Joey: Yeah, it's like a cow's opinion. It just doesn't matter. It's moo.
Rachel: Have I been living with him for too long, or did that all just make sense?
