Laughter is an emotional reaction to a cheerful and humorous remark . Such a reaction is to people even in a serious situation to be able to defend themselves psychologically when challenged . A man who has a sense of humor manages to make everyone liked . Everyone , despite a lack of experience , can develop a sense of humor . But humor can be of several types : offensive , insulting, sarcastic or vulgar (especially among youth ) and subtle satire based on popular (in people older smart ) . Usually very bold jokes can be used very good friends . For others an inappropriate joke could be interpreted as an attempt to ridicule , insult or to offend .
