A very rare occurrence when a song comes on and everyone sings with it because it is so familiar.
1. Today on the bus, "Hey There Delilah" came on the radio, and everyone started singing it. It was such a High School Musical Moment.

2. Yesterday, in art class, the art teacher turned the radio on. Everyone was silent until "Rock and Roll All Night" came on, then they started singing along; it was a total High School Musical Moment.

High School Musical is a Disney Channel Movie released on January 20, 2006. A sequel was released on August 17, 2007. A second sequel is to be released into theatres about the senior prom and graduation of the characters sometime in late 08-09. Yes, it DOES have nearly an identical plot line to Grease. However, it is Disney Channel's most succesful movie at this time. 33 countries have released this movie on Disney Channel.
Dood, seriously. If you really think High School Musical is SO lame, then why waste your time on it? No one cares if you hate it just because it is like Grease. I guess you must hate Grease then, because that is said to be a modern (at the time) retelling of Romeo and Juliet (although different, yes, but that is the basis.) So seriously, get a life. High School Musical is a good movie. Yes, it's corny. But honestly, I love the movie. And Zac Efron does help (:

A problem which is cause by being great at multiple things. Usually used to describe the troubles of a friend you don't feel bad for because their life is better than yours and they are great at everything.
Talented Person: I made the Musical and the Varsity Basketball team and I can't do both, but I am the star of both, what should I do?
Other Person: Well it sounds like you have a High School Musical Problem.

A "High School Musical" Jump is a picture taken of someone while they have jumped and are in mid-air. It is inspired by the popular "High School Musical" movie posters of the cast members jumping in mid-air (hence the title).
Joe: Let's take a picture.

Alex: Let's make it of a "High School Musical" Jump!

Joe: Alright.

Alex: Okay...one...two...three...jump!

(As they jump and are in mid-air, the camera takes the picture.)

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.

The girl would have dated the basketball player but then she would realize the black guy was better in bed because of his John Holmes. And then she would get pregnent and the basketball player would catch her cheating because they baby would be half black. Then him and the black guy would have a knife fight, while the girl is on the side lines doing some herion and then she drops the baby and it gets brain damage. Then when the baby grows up it will realize what a failure it is and it will commit suicide which would lead the teen mom and the basketball player into depression

The super awesome Disney movie that is hated by so many, which is so messed up seeing how it makes people happy and most people who hate it, only hate it because it has "so many fangirls" which is basically saying you hate it because it makes other people happy.

Also, people stop liking High school Musical because it is not "cool" anymore. But the truth is, High School Musical is a great, inspirational movie that has no violence, sex, or cussing in it and still gets it meaningful point across. Amazing isn't it?

And so what if it is over-advertised? That is Disney's fault, not the movie's.
HSM fan: Hey, did you watch High School Musical 2 over the summer?

Looser who decided it's not cool anymore: No.

fan: Why?

Looser: Because it's dumb and I never even liked it because there is no making out in it! Plus, it makes people like you HAPPY!
