A faus is a (usually) fat annoying person that grunts a lot. In general, nobody likes fauses and will just stare at them when they're not thinking about beating them up. Historically, fauses were thought of in many cultures as shape shifters that somehow got stuck in the guise of a walrus/humanoid creature. Modern science, however has revealed that they are humans indeed, but just in an extremely annoying form.
