街舞圈中，有一群特別的男舞者，他們擅長各種在台灣偏女性意象的風格。妖、騷、婊，是大家最常用來形容他們舞蹈肢體的詞彙。這群Girl’s Style男舞者帶給觀眾對於性別的不安全感，是這份研究的出發點，並且提出兩個研究問題，第一，他們性別越界特質的舞蹈實踐為何，反映了什麼性╱別意涵；第二，他們如何從舞蹈實踐中形塑自我。 為了解舞者的舞蹈實踐，本研究採取了參與觀察與深度訪談兩種資料收集方法，在校內熱舞社與校外街舞教室兩個田野點，集結近六個月的參與觀察筆記、近一年的相處經驗，以及四位受訪者的訪談內容，組成了可供分析的資料。研究者以舞蹈實踐、跨性別與舞蹈取向的自我，作為資料分析的三大概念，讓可見的舞蹈與舞者成為資料分析的對象。並且將舞者的自我等同於舞者的身體，其支持了舞者的吸收與抵抗，是舞者能動的基礎。 研究發現，這群特別的男舞者在街舞圈中，透過服裝、話語、性別腳本等多重文本的實踐，構成Bitch-Style這個新的意義系統，並且在實踐中翻轉了妖、騷、婊等污名話語，亦形塑跨性別的自我。舞者亦會在不同的情境中會自動調校性化的位置，以自我保護、展演符合社會期待的性別角色。未來期望更舞蹈與性/別的相關研究，能和本文的婊子們彼此激盪、對話。 / There’s a group of male street dancers call themselves “bitches”. Started with the uncertain feeling toward their sex/gender dancing image, the study tried to figure out what are their transgender dance practices, what kinds of meaning it contains with sex/gender, and how they fashion themselves by dancing. To understand their dance practices, the researcher took " Participant Observation" and "In-Depth Interview" as the two ways of data-collecting. After gathering with them for one year, I take dance practice, transgender performances and dance orientation of self as three approaches to analyze data. Self in this study is treated as dancers’ dancing body. In conclusion, the researcher argue that Girl’s Style male street dancers should be named as Bitch-Style male dancers. They form themselves by multi-textual practices such as discourses, dressing and gender script. Those insulting phrases like 妖、騷、婊 are transformed into positive words to them by dance practicing. Also, researcher found that they change sexed position quickly and well whenever they change scenarios. In the future,I hope there could be more researches about dance and sexuality which can support and dialogize with Bitches in my study.
