"Debaser" is a song by the American alternative rock band Pixies, and is the first song on their 1989 album Doolittle. The song was written and sung by frontman Black Francis and was produced by Gil Norton during Doolittle's recording sessions.
"Debaser" was later released as a single in 1997 to promote the Death to the Pixies compilation. The single appeared in three forms: live, studio and demo.
The lyrics are based on a French surrealist film by Luis Buñuel and Salvador Dalí called Un chien andalou. .
