Feung (it's latin name being feungsuei), is a highly transmissible and contagious virus. First appearing in 1760 amidst the beginning of the industrial revolution. Although its transmissibility is over 100%, the polio vaccine developed in the 1950's was able to destroy the feung, leading to a worldwide eradication of it. Some small clusters of the feung may exist, although being very rare.

Contracting the feung virus will make you get the Spewange ailment and in turn, use the Spewange dialect. Feung's symptoms may also be an elevated heart rate of 150bpm or more, and the ability to piss off anyone.
