Headphone Thrower 

When listening to a song on your headphones, you are so overwhelmed with the power and awesomeness of the music that you spike your headphones like a football when the song is over.

Elvis' performance of "American Trilogy" is a headphone thrower.

headphone-hint 

When your sitting alone (at work, on a plane, home or anywhere) listening to your music through headphones and someone comes over and starts to talk to you and you don't remove your headphones because you don't wish to talk to them.

Marie: *At work on her computer* "Music music music."

Rachel: "Hi Marie, how's it going today? So, omg I'm so worried about..."

Marie: *Looking directly at Rachel* "Music music music."

Rachel: "Marie? Hello?"

Marie: "Music music music." *Turns back to computer*

That is a headphone-hint.

Headphone Neck Syndrome

A rare medical condition requiring one to wear headphones around his or her neck at all times. Especially common among Western young adult/teenage males and promoters within the entertainment industry.

Young Adult 1: What's Mike got on his neck? Looks like a big chunk of metal.
Young Adult 2: Oh, he's got Headphone Neck Syndrome.
Young Adult 1: Is it contagious?
Young Adult 2: Very! The Beats by Dre type is the most common form of this blight.

Headphonalomia 

A serious disorder that causes an individual to go everywhere and do everything in life with headphones in/on their ears. Sometimes they listen to music. Sometimes they listen to podcasts. Sometimes they listen to the endless existence-questioning chatter of their own mind. The headphones bring a sense of brief anxiety-reducing comfort, like a tortoise and her shell.

I could tell that Cody's headphonalomia was progressing when I caught him at Grandma's funeral with his Beat By Dre's on.

My girlfriend likes to have headphones in when we have sex because she has headphonalomia.
