This is like one of those pantyliner commercials where they call them 'wings' (even though they're not winglike at all) and not 'flaps' which conjures ... different visual images.
Isn't a manbag just a handbag?
Or is it called that because it can't be called a mansack?
I say that no man should carry any bag with dignity except perhaps for colostemy purposes. And by then you don't have any diginity to speak of anyhow.
