arse gravy
A particularly noisome form of human excrement. Runny, smelly and not fully processed by the lower bowel. Often appearing shortly after prolonged and energetic anal sex. Can be used as an expletive.
I had to go very suddenly to the toilet, I could feel the arse gravy almost seeping out.
Arsegravy! Somebody's smashed my car!
