Term used to describe something displeasing or otherwise horrible. Imagine, if you will, a town, named "Crap Town" and what sort of things you would find in said town. "Craptown" should only be used to describe inanimate objects; it is considered very degrading to describe a person as craptown.
There is no way I am letting that craptown X-box into my house!
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
