gratuitous sequelitis means: This disease is only capable of infecting Hollywood film producers. The symptoms include excessive greed and complete lack of creativity. The producer will unload the steaming heap of junk and then label it with the title of the movie, plus “2”. This will then be given to an idiot audience who will pay money for a glimpse at the contents of the box. Gratuitous sequelitis can lead to extreme cases. Sequential sequel numbers reach into double figures in some instances. (in Community Dictionary, added by Matías Fuentes)
