Figure of Speech: Symploce (SIM plo see), the first-and-last repeater
Never mind that Mr. Diddy called a press conference to announce the retirement of a single letter. By repeating the first and last words of consecutive clauses, he pulls off a perfectly rhythmic symploce. (It means "intertwining" in Greek.) He splits an imaginary audience in two and joins them in a third clause. And he slows the rhythm at the end with three monosyllabic words: "can, just, chant, Diddy."
If more white people could talk like that, the world would be a better place.
Snappy Answer (in the tradition of Beavis and Butthead): "Now you won't worry about your 'P' onstage."
