A person who walks very slowly down a hallway void of any purpose. Hall zombies usually travel in packs of 3 or more walking shoulder to shoulder blocking others from passing.
Man, I was running super late for work this morning. When I finally got into the building, I could not believe I got stuck behind three hall zombies discussing last night's episode of American Idol. UGGGH!
An employee who never actually does any work. Hall zombies are often found making idle conversation in the halls or spend an inordinate amount of time in the break room. Often they have an appearance of always being busy and thus can go undetected sometimes for years, with the cluttered desk and laundry list of meetings on the outlook calender. A classic hiding spot is in a mid-level management position.
My boss is such a hall zombie, he never does anything.
