"Ratfinks, Suicide Tanks and Cannibal Girls" is a song by White Zombie from the Beavis and Butt-head Do America Soundtrack. This would be the last single, as well as the last song, the band would release before disbanding.
The song appears in the movie during a scene where Beavis and Butt-head are lost in the Southwest desert; both are suffering from dehydration, and the former has eaten a peyote cactus. Beavis experiences a mescaline-inspired hallucination, an animated sequence based on Rob Zombie's nightmarish artwork interwoven with Beavis and Butt-head motifs (such as the boys sitting on their couch or working at Burger World).
