The Dodge Viper is the most kick-ass car around. It totally owns the Corvette, no matter what anyone says.

An adjective that is synonymous with extremely cool, awesome, amazing, etc. Mostly used by people of the "hipster" classification, but is also common among others.

Originated from blogger Dan Bergstein on "Sparknotes."

(n.) A swift coordinated move, in which the attacker approaches an unassuming victim who is standing up. The attacker kneels down and, with gusto and vim, sticks his/her arm between the victim's legs and reaches up to pinch the victim's belly. As this happens the attacker yells out, "Viper!!" Please note, the viper must be done with care, lest contact with other organs is accidentally made. (v. to viper) to give a person the viper
(n.) Oh my god, I can't believe that guy gave me the viper!

(v.) That's right, chump! You've just been vipered!

Someone who can be cool, but is often calculating your every move on the inside. They can be deceptive and decietful, and appear to be all knowning at times because of people's predictability.

They often prey on your weaknesses, and notice all of your flaws just by looking at you.

However because of their ability to see indefinite flaws, they wind up hating themselves, because they see all of their own flaws in extreme detail.

In general, "Viper" would be the name for your sneaky, slightly badass, tough friend who's skilled at many things the average biddy would never dare to try.
I didn't notice how bad Jimmy's acne was until that Viper pointed it out.

She's such a viper, she looks all sweet but she's just using him for gossip.
