headphone check 

When you listen to a song you like in public but would be embarassed or emasculated if someone knew you where listening to it, so you pull your head phones down and check to make sure they aren't loud enough for other people to hear your music. Usaully if too loud you lower the volume or switch songs to avoid getting called gay if some one where to hear.

guy1 " dude did you see that guy during study hall he pulled a headphone check"

Guy2 " yeah I was sitting next while he was listening to Britney spears he pulled a headphone check to confirm his fear that I could her what he was listening to.

Janitor Headphones 

Headphones seen in movies and in TV shows being worn by janitors, usually used for jamming out to the latest cassette tapes; this can be seen in media from 1996 or 2016. The janitor is always the same person who’s wearing a bulky pair of 3.5 mm audio jack headphones (over ear, “noise cancelling”) or a cheaper pair of “on ear” headphones with an adjustable metal strip that goes over your head.

Person: "What are you wearing?"
Assumed to be Janitor: *Jamming out to The Cure on his walkman, mopping and not giving a fuck*
Other person: "Those are Janitor Headphones. He's probably a janitor.
