Ego is something that is causing most of the problems not only in whole world but also in our city. it makes one take too much pride in him or herself and when its broke or hurt usually reaction can be quite extreme in form of anger. some people just want to inflate their ego so they look for others acceptance usually in the form of compliment or praise  about their looks . you can usually see this on their social media posts some even beg for likes or good comments. and in this race for looking a "cool dude" they forget basic manners and start to believe that being rude to others will make them look cool and these are the same people who keep on saying "oh i am a nice guy but i cant make a female friend " 

even a simple no or difference in opinion with them can burst their ego out loud and they will always try their best to convince you. best way to handle such people is simply ignore them as one cant win against a person having so much pride in him or herself as a last resort some even throw racist remarks in order to cope with their destroyed ego so its best to just ignore , block and move on forward.
