Peripheral Wipe
A rectal wipe job that extends well beyond the anal sphincter cleansing and requires one or more wipes of the outer edges of or in as far as the middle of the butt cheeks. A common occurrence when suffering an assplosion of butt batter.
Holy Shite!!!! That was nasty. I just blew a wet brown demon out my arse and took me several peripheral wipes just to get the splatters.
