Tribangle

A religion (although many dispute it to be a cult) in which the followers worship the great and powerful Nigel Thornbury. The Tribangle has also developed its own dialect which most linguists describe as 'alien' and only Tribanglists can fully interpret. This dialect includes many peculiar words such as 'Ungo', 'Bungo', 'Bungalow', 'Stoob', and 'Croob'. For more information visit the Tribangle wiki.

Friend One: "Hey! Are you in the Tribangle?"
Friend Two: "Wait, isn't that a sex position?!"
Friend One: "Get stoobed you croob you are not worthy of Nigel!!
