look up any word, like fleek:
 
1.
A syndrome in which a team is so reliant on their superstars (and the rest of the players suck) that they can win regular season games but cannot withstand a playoff series and ultimately win a championship. This was first developed by the Cleveland Cavaliers when LeBron James reportedly gave up on several different occasions, and the team was never able to win a championship.
Dude, did you hear about LeBron taking his talents to South Beach?!

Yeah, and some guy named Chris Bosh did, too! He's apparently really good!

Dwyane Wade, LeBron James, and some guy named Chris Bosh... this teams gonna be great! But wait a sec, who the hell are all these other people on the team?

Uh oh... looks like Superstar Syndrome...

2.
When a human being ranging from teenager to adult cannot bear to lose in a sport related activity no matter the level, age, or sex of the competition.
"Why did Johnny just tackle Amanda? I thought this was 2 hand touch?"

"Well she was about to score, and Johnny has a bad case of Super Star Syndrome"

"I think she's bleeding"
