Aggression is a word that we utilize each day to portray the conduct of others and maybe even of ourselves. We say that individuals are aggressive in the event that they yell at or hit each other, on the off chance that they cut off different autos in rush hour gridlock, or notwithstanding when they crush their clench hands on the table in disappointment. In any case, other hurtful acts, for example, the wounds that games players get amid a harsh amusement or the murdering of aggressors in a war probably won't be seen by everybody as aggression.  

Social psychologists characterize aggression as conduct that is expected to hurt another person who does not wish to be hurt.
