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.

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.
