Berryhuckle
Meaning: A round of drinks (in Scotland)
Origins and History: Coined in recent times as a deliberate distortion on top of rhyming slang: “Huckleberry Hound” implies “round” (of drinks), and “Huckleberry” is then reversed – and not Spoonerized, as claimed by some commentators – to “berryhuckle.”
