Lammies Bleat in Aw the Fanks: We Knew it All Along, Didn't We?

I've still been dithering around over the word "fank," although I've been sidetracked a few times. Here is the final word, the real definition, quoted from the Dictionary of the Scots Language, a project based at the University of Dundee.
