Goblin Cock is a heavy metal band from San Diego, California started by Rob Crow of the band Pinback. Musically, they play a form of doom metal/drone metal with rather unusual lyrical subjects (e.g. the Snuffleupagus from the TV show Sesame Street). All members of the band have taken on stage names, two of which contain sexual euphemisms.
