UD Dumb Fuck 

You are a UD Dumb Fuck if you ever came onto Urban Dictionary to define someone's name that you know. The "definition" usually starts with "so and so persons are sweet and caring... blah, blah, barf!". Or it could be the opposite with "so and so person is an annoying asshole".

Either way it's fucking dumb because there are literally hundreds of names on UD which have the same lame definition because not only are these writers dumb as fuck but they lack the creativity to write an original sweet ode to the girl or boy who undoubtedly has them in the "friend zone" or is fucking someone else because that's what happens when you're clingy and annoying.

UD Dumb Fuck: Summer is as funny as she is sweet...

DJ (over loudspeaker): Summer to the main stage, Autumn to the Champaign Room.

(Music in the background): Ass titties, ass and titties, ass ass titties titties ass and titties...

Dumb fuck

The girl you just had sex with who thought a condom was something you put on a hot dog.

That girl I met at the bar was such a dumb fuck; I can't believe I actually fucked her.
