A confidence trick or confidence game (also known as a bunko, con, flim flam, gaffle, grift, scam, scheme, or swindle) is an attempt to defraud a person or group by gaining their confidence.
The first known usage of the term "confidence man" was in 1849; it was used by the press during the trial of William Thompson. Thompson chatted with strangers until he asked if they had the confidence to lend him their watches, whereupon he would walk off with the watch; he was captured when a victim recognized him on the street.
