Headphone Zombie 

When someone is wearing headphones and is completely unresponsive to the outside world. Headphone zombies often travel in packs, but rarely communicate or associate with one another. It is not yet determined whether they feed on brains or popular music, or both.

I drove through the University and nearly hit a pack of J-walking headphone zombies

Headphone zombie 

A soldier of fortune for the undead army. Headphone zombies attack mostly young people and turn them into headphone zombies. With larger numbers, the zombies have safety, and usually win, unfortunately.

They are trying to take over, and let the machines win. The mind of a headphone zombie is artificial intelligence, and it's contagious!
