talk one's head off, to
To be extremely loquacious. This hyperbole, also put as to talk someone’s head or someone’s ear off, implies that the boredom of relentless loquacity is making either the speaker’s or the listener’s head fall off. These expressions have largely replaced the earlier talk the hind leg off a horse/ donkey/dog, current from the mid-nineteenth to the mid-twentieth century. G. and S. Lorimer point out, in The Heart Specialist (1935), “An American will talk your ear off about his sport with a little encouragement.”Yet another is talk the ear off a brass monkey. See also like greased lightning.
