smart dumb nigga 

That guy who doesn't know what he's talking about but tries to sound like he does. Not very bright, doesn't make any sense (though he thinks he's really profound, on to something, etc.). He's not lying to you, he simply doesn't know any better, but will insist he's right, which makes him not worth the trouble of setting straight. Yes, THAT guy.

A very on-point term (coined by comedian Katt Williams in The Pimp Chronicles pt 1), because we all know one...or more.
Examples of smart dumb niggas would be:
-the chick who insists her Infiniti Q45 is front wheel drive when it's really rear drive
-the guy who spells the word "ludicrous" like the name of the rapper Ludacris
-most people who say overstand or conversate
-one who knows the Bible like the palm of his hand but argues the Earth is only 6000 years old
-most conspiracy theorists

You know a smart dumb nigga when you see one basically.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
