In modern Chinese, the verb dun (squat) is an intransitive verb. It often forms a structure of "dun + object" with the object of the place, indicating that someone or something does a squatting action in a certain place. In addition, other types of objects generally do not enter the structure. However, due to the particularity of the network language environment, this structure can be used in network communication without the constraints of modern Chinese grammar rules. Starting from the new usage of "dun + object" in the Weibo network language special zone, the article explores the syntactic structure of the new usage of "dun + object", further analyzes its semantics and generation mechanism, and finds that the new usage of "dun + object" conforms to the network language features. It is novel, unique, humorous and productive, and it also reflects the general psychology and cultural pursuit of netizens in online language culture.
