bench jockeying
n.— «Baseball not being a repository of deep thought, players on opposing teams used to stand in the dugout and hurl insults at [Jackie] Robinson. “Bench jockeying,” as it’s known, has a long tenure in the sport, but it’s usually focused on things like weight or facial features. In Pittsburgh one day, Greenberg was playing first base while a pocket of teammates hollered at Robinson: “Hey, coal mine!”» —“Baseball greats show how great they are after 1st-base crash” by Neal Rubin Detroit News (Michigan) June 14, 2006.
