A word commonly known in the food service industry by servers who frequently enter and exit the kitchen with their hands full. Servers call out "Corner" as they approach the entryway to and from the kitchen when they have trays, glassware and/or plates in their hands. The purpose of this is to warn anyone who may be approaching from the other direction, unseen by the person calling out "Corner" and thus avoiding a collision and the subsequential spill of aforementioned plates/glassware. Servers new to the industry usually find themselves saying "Corner" out of work when they approach a corner, and it is cause for much laughter and embarrassment.
