From the Latin "one who swags"

His cousin was none other than Jimmy Swaggart, renowned televangalist. And since Jimmy was underage at the time and a man, let's not forget, the Assemblies of God insisted that he be defrocked and punched in the face, a punishment from which he has never fully recovered.
