在肉身所出諸物之中，屎尿常被視為最污穢者。本文即在討論屎尿意象如何介入臺灣當代詩，彰顯其嶄新走向與精采變貌。通過諸多文本的檢視與分析，我提出三種主要的詩意生產模式：其一，鬱糞型，出於一種幽暗意識，以屎尿為魔鬼或罪惡的隱喻，極力想要排出而不能，因而鬱悶牢騷者；其二，潑糞型，刻意挑戰「斷慾離穢」的言說，以屎尿為反社會的武器，並藉此重新省視人的本質；其三，玩屎型，崇尚自由與解放，以屎尿為神奇變幻的遊戲，並藉此解構崇高精神、破壞宏大敘事。最後，本文又從屎尿作為詩法的面向，探討建立屎尿詩學的可能。

Excrement is normally regarded as the most disgusting among the things issued from one’s body. This essay aims at discussing how the imagery of excrement came to be a topic discussed in contemporary Taiwanese poetry, its novelty as a trend and its wonderful transfiguration. After a sizable corpus of works were inspected and analyzed, three main patterns of poetic production were apparent: First, the blocked-up excrement type, stemming from a gloomy outlook, uses excrement as a metaphor for the devil or evil. The desire to rid oneself of the foulness is unrealized, resulting in pent-up emotion and thoughts. Second, the splashing excrement type challenges the notion of “curbing desires and avoiding filth.” It uses excrement as a weapon for antisocial action, as a way to rethink what it means to be human. Third, the amusing excrement type advocates freedom and liberation, by viewing excrement as a magical and whimsical game. This is used to deconstruct things noble and to destroy the grand narrative. Finally, the possibility of establishing an “excrement poetics” is discussed.
