Cheepnis is a song by Frank Zappa written for his never-produced musical Hunchentoot, a tribute to B-movies. The song first appeared on his 1974 album Roxy & Elsewhere, from a live recording. Another live version of the song was released on You Can't Do That On Stage Anymore Vol. 2. The beginning of the Roxy & Elsewhere version of the track has a 2 minute monologue about It Conquered The World and monster movies in general, including Zappa's comment that "cheapness has nothing to do with the budget of the film, although it helps." The song talks about the general principle of cheesy special effects in early monster movies, including a monster, named "Frunobulax", that looks like a "great big poodle dog." The poodle is a recurring theme in other Zappa songs and is an illustration of what he referred to as the "conceptual continuity" of his body of work.
The song is mentioned in the Book of the SubGenius.
