Happy corner, also known as aluba (simplified Chinese: 阿鲁巴; traditional Chinese: 阿魯巴; pinyin: ālǔbā), is a form of prank, game, or bullying that primarily occurs in mainland China, Hong Kong, Macau and Taiwan, generally among male students, in which the victim is lifted up by several perpetrators who subsequently bump his groin against a pole-shaped object.
[2] A 2017 research paper that interviewed 45 Taiwanese men found that common motives for engaging in aluba include celebrating special occasions, punishing other students, and resolving disputes.
[1]: 26 Summarizing previous research, Li Peiwen notes that aluba allows school-aged boys to build intimacy with each other in a societal context in which gentler forms of physical affection may be perceived as indicators of homosexuality or effeminacy.
[5]: 235 In their 2017 paper, Bih Herng-dar, Huang Haitao, Hung Wen-lung, and Pan Bo-han dispute scholarly works and legislative efforts that have categorized aluba as a form of bullying.
[1]: 33–34 In a 2011 research paper, Bih and Huang also dispute the claim that aluba is a form of hazing, noting that in contrast to secretive initiation rituals, the practice generally occurs in the open.
