Most commonly occurring in a committed relationship or close proximity roommate situation. It is the act of putting ones own show/music/etc on speakers before the other domestic resident can put theirs on speakers, thus forcing them to use headphones. Most relevant when the other party had theirs on speakers first, and due to an interruption they paused/muted their sound, and upon cessation of the interruption, the first party puts their audible content on speakers.

- Hah! Speaker Jacked, bitch!
