Abstract: Two predominant discursive expressions,"steganography" and "marking",have emerged in current online communities,each representing an extreme in "restraint" and "expressiveness".This dynamic has given rise to a discursive relationship between "implicit discourse" and "extreme discourse"."Speaking without straightforwardness" has become a significant feature of online folk language,extending from early discussion boards and forums to today's social media zones,gaming communities,and major platforms.Online implicit discourse is almost synonymous with "memes",sharing metaphorical similarities in word formation as well as metonymic connections.The marked cultural characteristics of extreme discourse represent a form of "discursive appropriation",even evolving into online bullying.From the perspective of cyber pragmatics,the illocutionary acts of these polarized discourses are linked to social resonance and meme-driven amplification.Since both implicit and extreme discourse belong to online subcultures and reflect internal differentiation within "heteroglossia" rather than opposition in value positions,it is necessary to view them as an integrated phenomenon in online language games and implement discursive governance and standardization.In an era of increasing social differentiation and individuality,acknowledging "differential consensus" during transformation and change,examining the construction of polarized discourses through relationalism,and discerning whether these discourses represent well-intentioned reminders seeking social consensus or counter-discursive expressions of hidden transcripts are crucial steps for accurately assessing current social attitudes and emotions,forming an essential basis for the sound governance of online discourse.
