From Calling England:
It reminds me of the famous story from the Korean war where 600 British were under attack from 10,000 Chinese soldiers, and the British brigadier; Thomas Brodie reported to the American Commander that the situation was "a bit sticky, things are pretty sticky down there" i.e. hurry up with them reinforcements - now! Needless to say to the Americans the phrase; "a bit sticky" didn't quite have the same urgency.
