Sandwich beeyotch
The person designated to pick up lunch by coworkers based on availability. An individual is more likely to be assigned sandwich beeyotch responsibilities if they are new to a company, straight out of college, or happen to be standing around with their hands in pockets by the time coworkers get hungry. Sandwich beeyotches are not limited to picking up sandwiches.
