Patrick Weston Joyce,
English as we speak it in Ireland…
(1910)
“ When a man declines to talk with or discuss matters with another, he says 'I owe you no discourse'—used in a more or less offensive sense—and heard all through Ireland. When a person shows himself very cute and clever another says to him 'Who let you out?'—an ironical expression of fun: as much as to say that he must have been confined in an asylum as a confirmed fool. ”
