A sub genre mixed of grunge, 60's garage rock, and blues. It is loud, untuned, and fuzzy guitars backed by loose drumming filled with toms and crashes. Usually only consists of two or three members. Short for sloppy rock n' roll. Sounds almost unrehearsed and raw.
"We're seeing a slop rock band tonight, called Vitamin OverDose, we really love the raw vibe."

"I just got The Jeff the Brotherhood cd, it's so slop rock"
