Jagger is a complete jerk who will often try to befriend you, but only if you have something they want. During this time they will insult you, try to embarrass you, and when you do that back to them in a much nicer more playful way, they will get pissed and often times go into a tard rage on you. You best start running when this happens, because this motherfucker can’t take a goddamn joke to save their life.
That guy is such a jagger. He got pissed at me because I called him an asshole, even though yesterday he told me I was a worthless piece of garbage! What a dick.
A complete dick. The one who tries his hardest to be with the "cool kids". The one who always has to get his way, and always has to have the better stuff. A jagger will most likely try to be funny, but man when you make fun of him... he gets pissed.
Me: "He is such a jagger"
Kyle: "I know right! He left me in middle school to hang out with the cool kids!"
Me: "Unbelievable..."
Kyle: "Not only that but I got a hundred dollar bike and he went out and got a three hundred dollar bike!"
