“Exactly how long is a cotton picking minute?”

“Now wait just a cotton-picking minute!” means the same as “Now wait just one damned minute!” There is no exact measure of time.
 
“Well, here I am. Hey, just a cotton-picking minute. This don’t look like the Coachella Valley to me” was in the Bugs Bunny cartoon Bully for Bugs (1953). “After the victory, the favorite expression with the South Carolina contingent Saturday night was, ‘Wait a cotton pickin’ minute!’” was printed in the Greenville (SC) News on November 17, 1953.
 
“Cotton-picking minute,” as used in the Bugs Bunny cartoon, did not have a racist intention, but the term is often regarded as racist and generally should be avoided.

How long exactly is a “Cotton picking minute”?
is it 60 seconds, like a standard minute?
Best Answer:  For the benefit of the above posters, a cotton-picking minute (CPM) is most definitely not equivalent to a NY minute (NYM). Anyone who lives in the State knows that a NY minute comprises less than 60 seconds. (...) A cotton-picking minute, on the otherhand, actually comprises a period of time longer than 60 seconds.
