DYKWIA
n.— «I’m told Ally had lost his voice and was ordering drinks by sign. L for lager, ML for more lager and DYKWIA for do you know who I am? This came in handy if lager was ever refused. And if he was really bad come closing time, he had DYKWIL—do you know where I live?» —“A Dutch Out of Order” by Alan Mcmillan Scottish Daily Record & Sunday Mail (Glasgow, Scotland) Apr. 21, 1997.
