High School Musical Syndrome 

When the main character in a production (Mostly Disney) that appears on either television or film such is normal in the beginning, shallow in the middle, and becomes normal again in the end, realizing what a total dick it was. I just call it HSM syndrome because it's one of the most obvious film you would see it in.

Troy Bolton in HSM 2

Jo in Mean Girls 2

Kady in Mean Girls

They are all clear examples of High School Musical Syndrome. If you don't believe me look it up for yourselves.

High School Musical Syndrome 

Feeling that kicks in when a girl watches some romantic movie, usually Disney like High School Musical. Girl gets romantic vibes on the perfect romantic guys in the movie that do romantic stuff to show their love. After seeing it, girl starts to judge her own relationship or loses interest on normal real guys, because reality seems way too simple to the new high standards caused by a movie. Also -- HSM Syndrome.

"Why won't he drive his way to my house in the middle of the night, because that would be just so freaking romantic, but nooooo guys are just way too "lazy"!"
"Oh gosh. What a total High School Musical Syndrome..."
