This is a synonym for the anus which is typically used in porn. It is referring to the fact that a nice arsehole is often a tasty treat, as well as a functional tool for shitting.
It is usually used when referring to the very neat and tidy arsehole of a young female pornstar, often during the performance of a rimjob. However it is also used to refer to arseholes of any denomination, colour, size, shape, gender, sexual orientation or ethnicity.
"Oh wow, don't you have a neat little arsehole! I can't wait to dig my tongue right into your chocolate bon-bon factory!"
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
