grease someone's palm/fist, to

To bribe someone; also, to give a gratuity. This term has been around since the sixteenth century, and apparently a version of it was known even in Roman times, when Pliny the Younger called it unguentarium, translated as “ointment money” (Epistles, ca. a.d. 98). “Wyth golde and grotes they grese my hande,” wrote John Skelton (Magnyfycence, ca. 1529).
