One who talks for no reason other than to meet their daily word quota. A nonproductive speaker. One who is starving for attention and reaching for it with their tongue.
Etymology: The words stems from the contrast between a constructor,(one who hammers nails into boards in order to build something) and a boardnailer,(one who does not see the bigger picture, only thinks that hammering nails is in and of itself productive).
Steve - "My girlfriend is such a boardnailer. When I get home from work I just want to relax, but if Jen hasn't hammered her nails for the day I have to listen to the racket"
Marcus - "I feel you. Get her a girlfriend and a treadmill, that's what I did."
Simon - "It's weird, my wife can talk for an hour without saying a thing"
Jason - "So, you married a boardnailer. I'm sorry.."

You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine. Do you know that the orange lodges agitated for repeal of the union twenty years before O’Connel did or before the prelates of your communion denounced him as a demagogue? You fenians forget some things. (James Joyce, Ulysses. Penguin Books,1992. p. 38)
