chumbolone
n.— «“I gave him lip service,” Doyle said. “I didn’t know what he was talking about. I don’t wanna look like a chumbolone, an idiot, stupid,” Doyle said from the witness stand. There is a tasty Sicilian Easter cake called ciambellone, but Twan doesn’t look like a tasty Easter cake.» —“Playing dumb is wrong prescription” by John Kass Chicago Tribune Aug. 24, 2007.

John Kass of the Chicago Tribune made great use – again! – of “chumbolone” in his 2/7/09 column. Very entertaining!
