(n) politically correct replacement vernacular for pussy (i.e., "weak and ineffectual male" or "coward") per sex columnist Dan Savage. Based on the idea that the pussy, which can take a pounding, spit out offspring, etc., is is a far stronger organ than the scrotum.
"That lumbering jackass who called that smart, interesting guy a pussy? Total scrotum."
