A tribe of overly large people situated in Laos and southern Thailand. The Sihavongs are significant for their overly large weight, tendancy to spout out nonsense, and idiotic eccentricies. Alternative names for the Sihavongs include Fatmanscoop, Giant Asian and 'OH SHIT DON'T SIT ON ME!'.
Jim: HOLY SHIT DUDE THAT SIHAVONG JUST SAT ON JOHN!
