Abstract: With its frontier anecdotal story style,Snopes trilogy breaks the boundaries between genders,classes,things and people,whose text has the grotesque nature of great tension and interpretation.The grotesque in Bakhtin's theory is related to the southern literature of the United States.The grotesque in Snopes trilogy is exactly the embodiment of the tearing up of the southern society,including folk anecdotes without "grand narrative",grotesque figures of the South and the decrowning of faith.
