AIG
Arrogance, Incompetence & Greed, Inc.

The new name given to failed, mega-conglomerate, American Insurance Group, for taking $170 billion in federal bailout money with the right hand and, with the left, doling out $165 million in bonuses to the same execs who ran the company into the ground in the first place.

Now the universally recognized symbol for corporate greed and/or corruption.
For the American public, AIG now stands for "arrogance, incompetence and greed," (credit Rep. Paul Hodes, D-N.H. Mar. 18 2009)
