Whisky Galore

just found this one out

it's from the Irish "is maith sinn"

pronounced : is my sinn

literally "this is good"

also check out the route of the word "Galore"

Don't forget the Scots spoke Gaelic too!
The film of Whisky Galore was released in France as Whisky, a-Go-Go. It enjoyed such success that a night-club was opened bearing the name, and the phrase came into common usage.
