Bad Mood Guy is the seventh studio album by the Australian experimental group Severed Heads, first released in 1987.

Upon its initial release, the album met positive reviews with critics, one in particular referring to it as "punishing pop with crunching rhythms".

[3] The album's lead single "Hot With Fleas" did well on independent radio stations, peaking at #4 on Rockpool's dance charts during the week of 31 December 1987.

[5] In 2023, the UK label Futurismo, Inc. released a remastered version of the album on two different pressings of 2LP set (with the first LP on either "Fleabitten Rash" (purple with hot pink inkspot) or "Jetlag Metal" (solid metallic silver) coloured vinyl, and second on standard black) containing a 12-page "Bad Mood Booklet" styled after the zines Ellard would publish and sell via mail order in the mid-late 80s to augment the albums.

They also released it on CD in a standard Digipak with a foldout insert reproducing parts of the booklet.
