Watching a grown person cry after losing to a competitor that they assumed they were superior to, finding out that they are not. Then later, instead of admitting the other team was better, you explain how you had some unrelated problems that impacted your ability to focus to use your full potential. You then start to cry some more and make it so pitifully about you (and not about the better team that beat you) that you become the center of attention.
It occurs in sports, politics.
Everytime the lakers lose a championship (especially to the Pistons or Celtics) they do that.
Hillary Clinton acted like a Laker when she lost to Obama.
Watch Kobe literally cry like a Laker.
The Tea Partiers are a bunch of Lakers
