Benedict Arnold

old-fashioned A traitor. (Benedict Arnold was a US general during the Revolutionary War before he notoriously defected to the British Army.) Primarily heard in US. Look, just because I'm going to work for a different company doesn't make me a Benedict Arnold or anything. It isn't personal, it's business! That lying, two-faced Benedict Arnold sold us out! The gang was determined to find the Benedict Arnold who told the police about their illegal activities.
