Yabber

Yab'-ber

To talk or write utter nonsense and drivel, despite good intentions, in the manner of the well-known Britsh social commentator Yasmin Alibhai-Brown. I won't even dignify her with a link, but she was prattling on in today's Independent newspaper if you want to find some real yab-bing. She means well and aspires to good liberal values. But it would help if she talked sense.

I thought it might be a new word for the urban dictionary. But it already exists. Just not with this etymology.
