Corruption of the phrase '
in the privacy of your own home' to imply
sexual activity being the reason for being away from public view. First used in an
Alan Partridge sketch by a
British Lord justifying
pornography by claiming that "what a man does
in the privacy of his own attic is his business and his alone".
Of course, the suggestion is not that one must own an
attic in order to partake in
furious masturbation, nor, conversely, that
attics are only to be used for such pursuits. It is simply the
juxtaposition of a familiar phrase with a location particular to one person, and therein lies the genius of the piece.
Now, if you'll excuse me, I've got some private business to attend to in my
garden shed.
