Bork! Bork! Bork!
From Guild Wars Wiki
Bork! Bork! Bork! is a joke language put in by the designers of the game. It is based on the Swedish Chef, a character from The Muppet Show.
It works like any other language option in game, except that it doesn't have an associated spoken language for cinematics. Instead, English is used, but with Bork-subtitles. If you are in the European territory with this setting on, you are sent to the English districts; there are no Bork-districts.
[edit] Example
This is the Hall of Heroes victory message. It is based off English but written out as speaking with a deep accent.
