Egg-sellent point, my friend! I know my volleyball coach in the 7th grade was like that.
My brother's football coach in hs had a saying when he wanted the defense to step up.. "Quit playing butt-darts with the linemen and HUSTLE!" lol
I played basketball in high school and, admittedly, we let the language fly a bit during practice. When I was a senior, some freshman's mother came into the last 30 min. of practice (which was the first mistake) and she was offended by some of the words she heard. She complained and our coach begrudgingly gave us a talk the next day. There was a complete moratorium on cussing, including him. Anyone caught breaking the rule would have to run laps after practice. We went about two days being good until one guy made a stupid play and the coach yelled out, "What the f**k was that?" We all turned, he hung his head down and just muttered, "S**t". We all laughed. To his credit he ran the laps after practice, but the next day he told us the rule was gone and just to be careful as to who was in the gym if we let it fly.
