When you insist something excessively, it becomes known as cheerleading. This is because cheerleaders constantly remind us that yes, cheerleading is in fact, a sport. No matter what the occasion is, if you glance at a cheerleader she will most likely yell, "ITS A SPORT". Hence, "cheerleading" happens when something gets told over and over again, but really has no effect on anything at all.
