quicko: to make a move

While this might be applied in the romantic sense as well, what it really means is "I'm good and ready to go, but can't be bothered to find a subtler way to say it." (i.e., you're making a move towards going home, and do generally leave almost immediately thereafter) In considering further, I think the Brits actually use this significantly more than the Aussies, but the Aussies do use it significantly more than us Yanks.
