A Usenet joke newsgroup that follows the form of alt.swedish.chef.bork.bork.bork. It was cute when it started, but got old really really quickly. The original was named after the Swedish Chef from the Muppets who spoke in a stereotypical Swedish accent, saying "bork, bork, bork" after stuff.

Other examples of Swedish Chefisms:

...and many, many other newsgroup with three identical trailing words. Most of these newsgroups are extinct, with the possible exception of alt.adjective.noun.verb.verb.verb
