metalepsis is a figure of speech in which one thing is referred to by something else that is only remotely associated with it. Often the association works through a different figure of speech, or through a chain of cause and effect. Often metalepsis refers to the combination of several figures of speech into an altogether new one. Those base figures of speech can be literary references, resulting in a sophisticated form of allusion. A synonym for metalepsis is transumption, derived from the Latin transsumptio invented by Quintilian as an equivalent for the Greek.
Oh, I know. I looked it up. It still sounds kind of nefarious. "We're sorry to tell you this, Mr. Studsberry, but you have Metalepsis. Your dick is going to fall off."
