Muckle Flugga. Sounds a bit like a 'diss' you might get from a ruffian with a speech impediment, or like when they used to put Robocop on ITV and really badly dub over the swearies.
It's not though, it's the name of a splendid speyside distillery which has produced a blend and a single malt for all of our benefit. Good on 'em.
