A Shifty is a person that thinks he's the best, blames other people for his mistakes and doesn't understand that people do not always have time for him of things he's busy with. He generally gets mad at the people he doesn't understand.
Me: Hey, I can't make it tonight, sorry. (For let's say: Battlefield clan war)
Shifty: Then just don't come back idiot, we don't even need you anyways.
Friend: Why does he have to be such a Shifty?
1.A person, (usually male) that instantly causes alarm when they appear in a room. Usually seen in black, grey, or variety of cammo patterns. Should not be trusted.
2.A strange aura of energy that follows a person. Nothing is obvious, but all get the feeling that something is odd. Everyone IDs the person on sight.
