A hand or face towel used to polish up the rectal area after leaving a sloppy wet stinker in the toilet.
guy 1: Fuck it! What is this brown stain on my face towel?

guy 2: Oh, my bad, I thought that was a taint rag. I had to do some maintenance after that sloppy wet turd I just unloaded in your crapper.
