When someone has a flat ass and it looks like the back of a square shovel.
Oh my God..did you see the guy that just walked by? His pants are baggy in the back. Ya, he has a shovel arse AND there is no cure for a shovel arse.

The arse belonging to somebody who frequently participates in anal sex, acting as the passive partner (the one having their rectum penetrated). In such a case the arse is referred to metaphorically as a shovel, due to the fact that it "shovels in a lot of cock".
Aaron really loves taking cock, he's got a shovel arse!
