A fraternity or frat was a type of Earth group often found at schools.
While talking with Zhaan about how Aeryn Sun and Ka D'Argo were treating him, John Critchton said that it was like he was "in some never ending frat hazing at Alien U." When Zhaan asked "Frat... hazing," Crichton said that he'd rent her a copy of Animal House on the next planet they stopped at. ("Exodus From Genesis")
- The reference to fraternities was not in the original television release, but was only in the extended version of the episode found on home video.
