LEAK
Put in caps because it is used in the news every day, both with regard to the release of classified information (Afghanistan) by Wikileaks, and the oil that gushed from the BP well in the Gulf of Mexico.

Terence (2nd century B. C.), wrote a play in which one of the characters gossiped confidential information; "I am full of holes. I leak at every point."

Leak mostly meant the drip of a faucet, or other low volume release of liquid. Referring to the wholesale release of confidential material about operations in Afghanistan, Prof. Feaver of Duke Univ. said "To call the torrent a leak is to insult the laws of thermodynamics."

To call the torrent of oil that gushed from the BP well a 'leak' also seems inadequate.
