Does all the crappy jobs in the office no-one else wants to do. Maybe involving going around town getting keys cut or popping over the post office to pick up post too.
You want me to do what? Throw that over to Dave, the office bitch!
(n). The one person in a workplace, often a woman but not exclusively, whose job functions seem to be limited to making her coworkers' lives as hellish as possible and as underhandedly as possible for as long as possible in her unstoppable quest for unmerited power.
Do you know that office bitch made the company lose thousands of dollars just so that her rival would get fired?
