WEBDec 25, 2011 · Here’s the OED’s etymological note (lightly edited): First mentioned in 1772 as a new piece of fashionable slang; possibly of dialectal origin; Moor 1823 records it as a Suffolk word, and Jamieson, Supplement 1825, has flabrigast, 'to gasconade' [to boast extravagantly], flabrigastit 'worn out with exertion', as used in Perthshire.
