Abstract: Internet decadent phenomena reflect the mentality and situation of contemporary teenagers,in which the negative emotions are the symptoms of communication in the Internet era.The rise of negative emotions on the Internet is asubcultural practice due to the survival dilemma caused by stratum solidification,and the social loneliness caused by the changes of the times.With the help of media technology,this subcultural practice finally evolved into the life label and symbolic meaning of emotional catharsis and self-satisfaction.Negative emotions on the Internet show the narrative style characterized by decadence,confusion,making a fuss about nothing and sentimentality,which presents three cultural meanings:from an individual point of view,it is a tool for confirming identity and value identity;from a cultural point of view,it conveys gentle resistance to real life and mainstream culture;and from an economic point of view,the essence of this style is to turn the audience into "digital labor" and provide businesses with "digital goods" freely,and immerse themselves in them.As an Internet subcultural phenomenon,the excessive spread of teenagers' negative emotions lurks ideological worries at the social and personal levels,which might be resolved through measures such as external acculturation and subject self-discipline.

Key words: internet decadent phenomena, teenagers, negative emotions, subcultural style, internet ideology
