The term given to the complete inability of our European brethren to line up in an orderly fashion and wait their bleedin' turn resulting in anarchy and further queuing. However does usually have the added benefit of being able to find fellow Brits in the queue as they're often the ones shaking their head and/or tutting in disgust. Most often observed when waiting for an uplift at a continental ski resort.
Can also be used if you feel like jumping a queue.
Bartholomew: Where the frigg are you?
Archibald: I'm stuck in a Euro-queue.
Bartholomew: Unlucky, may I suggest windmilling through the crowd?!
