In popular culture, usually films or video games, the name "Beni" is used for characters in the story who are usually cowardly, comedic and tend to be in antagonistic roles; they are the characters who survive conflict by narrowly avoiding death, usually until the end of the film or game.

Named after Beni Gabor, the former Legion soldier and former comrade of Rick O'Connell, who had hidden himself in Hamunaptra during the Bedouins' attack from the movie, "The Mummy".
