There are always people who get their kicks by tormenting someone else. They enjoy insulting or teasing others, because they themselves are insecure. They are obviously completely jealous of something you have - your looks, luck or friends and family so just think wow that's a compliment! They get pleasure out of watching the person who they have insulted or teased squirm, feel uncomfortable or cry. Their main purpose is to get a reaction out of the other person. They are known as "Bullies". They look for a comeback, they expect it, so don't give it!
However you should also be advised that in America, and many other countries, it is a customary "initiation" procedure into a group. Often newcomers will be scolded, because they are newcomers, as a test of their resolve. Often friends will remark to other friends, “You’re so stupid!" in a joking, sarcastic way. It is your job to figure out if the other person is bonding with you via cynical sarcasm, or if their real intent is to publicly hurt you. If they are trying to “bully" you, you should follow the steps below:
1. When someone insults you, or remarks unfavorably about your looks or your clothes, just smile, and nicely say to the person, "You really think so?, I have been told my looks are very nice, but maybe I will have to change my hair style (or whatever they had made fun of)." Walk away. If you don't engage the person in a combative remark, he or she has nowhere else to go and has nothing else to say.
2. Remember that a person cannot fight or argue by himself. He needs someone to do this with. The only way anyone can hurt you is through physical contact. Words alone can only harm you if you allow them to.
3. Just turn around and walk away.If he/she insults you upon your intelligence, just stand there and very nicely tell him, "Oh you think so? Well maybe I will have to study more." Then walk away, holding your head up high.
4. Try not to show your feelings if you are insulted or teased. The more you act hurt, the more the insults will continue. The goal is to hurt you, but if you do not show you are hurt, it will stop. Sometimes they will continue for a while, but if you just show you don't care, they will eventually give up.
5. If someone insults you as BEING someone you're not, the best way to diffuse that is to sarcastically and grossly play out the part of who they're telling you are. Most of the time, people who insult others for being something, they are most afraid of being called that same thing themselves. Acting up as that person and saying "Hey you're my best buddy too!" or "you know you're my lover, right?" will make them stop quickly, and people around you will know you are kidding if you are wildly acting it out. Just don't hurt anyone in the process.
