Guy: Why do you talk like that?
dumb stupid fucking bitch: I use Urban Dictionary for my synonyms.

Get the Urban Dictionarymug. 
a cesspool created by the filthiest of swine and frequented by flies, cockroaches, rats and other filth and was created to promote these filthy creatures own definitions.
person a: do you know of a good online dictionary? is urban dictionary any good?
person b: LOL!!! you're joking right...? that so called "dictionary" is nothing but a collection of dung from filthy scum contributors. the low life swine who created the site won't even let you publish respectable real definitions. they only accept filth that those so called contributors' tiny brains could come up with. they want to promote these filthy definitions over real ones. it's really weird. but maybe it isn't; low life scum will only accept filth.
person a: thanks for telling me in advance.
