A dumb rat who likes to eat. She has two belly buttons, three knee caps, one eye, and is covered with fur. She can lick her elbow with her long nose. She smells like a trashcan. Her looks and smells can kill.

A word to describe a group of smelly and lazy people.
Jack and Jill walked by a group of smelly and lazy people, "look, Jack it's a Sianna" said Jill.
