Grundella Queen

The head cafeteria lady at every high school usually described as having very thin stringy hair, over weight, unusually surly and who's aptitude for serving quality low price meals is only matched by the beauty of her giant mole on her face.

There's a good chance she has some Eastern European decent. For example from Bulgaria or The Republic of Grundelslava.

Common first names include Alice, Dorris or Helga.
