Well, see jerk is someone that doesnt give a DAM, and girls like that! Jerks smoke, act like BADBOYS, hangout with many chiks, and just dont give a dam. I used to be a nice guy, but when i transfered to HIgh school things changed. Well it doesnt matter who u r, CONFIDENCE is all that matters. NICE GUYS dont have ****, they r too DAM scared to become someone they wanna be, they always complaining to themselves that they r ugly, poor, and have no friends and confidence, or whatever. To me all the jerk is, is the guy thats full of confidence. He lives a live like there is no tomorow, he doesnt care if the girl will dump him, or if the guy will kick his ass for stealing his gf, or if his mom gets upset becouse he came drunkk from the party! NICE guys, what can i say they think too much, And when the life is about to end, they die without even having fun. DON JUAN is the guy who has both, he is like nice guy and the bad boy and the jerk, He has carrier, women, and happines in his life.
