Adjective: Possessing a certain shoddy
mid-70s
aesthetic that's neither psychedelic nor
edgy, but just sort of hazy, slouching, and brownish. Usually associated with a failed attempt to be hip, years behind a given trend (i.e., still wearing bell-bottoms in the early 80s).
Canonical examples include Rankin and
Bass's animated film "The Hobbit", the band Bachman-Turner Overdrive, the original televised Scooby
Doo, municipal museum dioramas, and balding men with ponytails.
Note that sloobiness implies a lack of polish, tightness, and intentionality. For example, Cheech and
Chong may appear slooby on the surface, but the effect is too deliberate and legitimately funny to be slooby. If something is or ever was
cool, then it is not slooby; it's just vintage. Similarly, while The Dude would certainly be considered slooby if he were a real person, the film "The Big Lebowski" is a masterpiece and is not in the least slooby.
