: How did the phrase "DEAD NUTS ON" start?
I couldn't find anything to do with "nuts," dead or otherwise. In "British English A to Zed" by Norman W. Schur, it does have "dead on" as slang for "on the nose," with a reference to "bang on." "BANG ON - Slang. Exactly as planned or predicted. Literally, bang on target, of World Wars I and II vintage. Synonymous with 'dead on.' See also bang; dead on; spot-on."
