revolving bastard
n.— «I have had a fine encounter with Pappy Selznick. I wrote you about the requirement that I send publicity to Birdwell. Well, Birdwell is the revolving bastard if there ever was one. (The Revolving Bastard, in case you don’t know, is a bastard any way you turn him.)» —Jan. 15, 1939. (source: Double-Tongued Dictionary)
