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.

Whilst an unexpecting victim is standing, or more preferably bending over, another person approaches with index and middle fingers extended and sinks them into the man's grundle/gooch/taint and proclaims victoriously, "Viper!".
A very painful and startling move that must be executed with precision otherwise the awkward, "why did you just stick your fingers in my ass you fag?" will surely follow.
"So this douche was bending over tying his shoes, and I went over and gave him the worst viper in the world. He actually jumped over the bench he had propped his foot up on."
