Jukebox sabotage is a form of implanting one's own music into another person's mind by singing or whistling a tune around that person. If successful, that person will then begin whistling or singing your song minutes later.
I whistled “Mary had a little lamb” around my friend Matt one afternoon and then 5 minutes later I heard him whistling it down the hall. That is a textbook Jukebox Sabotage maneuver.
A friend whose LJ username begins with an X will giggle at this. -_-;;;
