The condition where someone thinks he or she is better than anyone else much like cheerleaders act in high school. These people are easy to spot, since they are usually snobbish and demeaning to those around them. People with Cheerleader Syndrome are usually middle-aged and are low to mid-level office management but think they run the entire company. Their attitudes make others think they are assholes; a title not entirely undeserved. Little do they know that many of their subordinates can do their job, but they cannot do the subordinate job.
Joe-"Paul sure is stuck-up. He thinks he is a gift to this company."
Bill-"Yeah, he has Cheerleader Syndrome."
Joe-" Yeah, but he needs to realize I can do his job, but he can't do mine."
Bill-"A moron can do his job....no offense to you, of course."
When every action is seen as wonderful and receives exaggerated praise, regardless of how truly awful it was.
Like at a sports event when the team is losing so bad they just want the game (and their shame) to be over, yet the cheerleaders still (have to) go out and cheer 'yeah Team - you're the best'.
When what should be said is 'You Suck' but instead what's said is 'good job', 'keep at it', ... that's the Cheerleader Syndrome.
Frank: Did you see that? Why are they cheering? Doesn't anyone realize how bad that sucked?
Miles: Yeah, it was awful. Looks like the cheerleader syndrome has taken over.
