Fountains of Varnoth 

Place where people who are cheesing their balls off can swim with the Itty-Titty Fairies of Mammary mountain.

Gerald Broflovski and Kenny McCormick were both seen getting high on cat urine which is referring to as "cheesing" in the South Park episode Major Boobage. While in their "cheesed" state they would enter a world heavily influenced by the 1981 film Heavy Metal where they would set out to claim the boob princess and lather her rockin tits in water. They would do battle in a variety of arenas such as the Breastriary, and get to swim in the Fountains of Varnoth, none of which were real since they were just cheesed out of their minds.
