Smug F*uckers (Noun) Refers to people who are so goddamn full of themselves, so obliviously arrogant, and so twitterfuckingly annoying that you'd risk a prison sentence for the opportunity to kick them in their goddamn perfectly white teeth just to see them cry.
Seriously--who the heck are these annoying people that keep popping up and why is one of them walking around in a wrinkled nightgown?
