someone who believes he is far superior to others , who only thinks about himself and his needs not caring if that hurt others in the proces but at the same time he is in need of admiration and attention of others so he always tries to keep a good image, he is childish in comportament easy to anger and irritate but of course that childish personality of his doesn't make him harmless !! verbal violance is his speciality , he'll make sure you always feel worser than trash ,tremple over your pride , all to make himself feel better.

well, that's what i know ,hope it helped!!
