Smartanus

Mostly male person who enjoys ending friendly arguments over scientific matters, which could have gone for hours and would have entertained both the people arguing and the audience, by pulling out his smartphone and declamating "on wikipedia, it says..". Is closely related to the hipster. The smartanusness of an individual is inversely correlated to its self-esteem and penis size.

John: "Man, I am totally sure! Tomatoes grow on trees!"
Jack:"Dude, where do yo get this from? Tomatoes are roots!"
Corey: "On Wikipedia, it says..."
John: "Put that phone down, you Smartanus, or I´ll shove it up your ass!"

It's Sampson, Smartypants! 

What was said to Thurgood by Sampson in the critically acclaimed and cult status movie, "Half-Baked".

Basically the scene entails Sampson calling Thurgood to set up a meeting with "Mr. Nice Guy", who is the accronym that Thurgood and his friends have decided to use while selling marijuana to bail their friend Kenny out of jail, certainly a movie worth checking out if you havent yet. Hilarious.

Thurgood: Whose this?

Sampson: It's Sampson, Smartypants!, put Mr. Nice Guy on the phone!

Thurgood: (pretending to be operator) "Emergency breakthrough", Sampson its Shiela, Mama fell!

Sampson: Shutup bitch!!

You a real nigga now boy, ol green eyes gonna miss ya!

Kenny: Hey girl, you hungry?

Fat, Nasty Black Girl on the street: Fuck you Nigga !!!

Kenny: I'm sorry I was talking to the horse.
