This study on taboo words focuses on the observation of use of palavrões in nine episodes of the comedy series Porta dos Fundos (PdF) as portrayal of discursive practices of residents of the city of Rio de Janeiro (Cariocas), primarily through theories of: Lexiculture (Galisson, 1988); Semantic and Pragmatics (Goffman, 1967; Camara Jr., 1981; Jay, 2008; Carretero, 2011); Interculturalism (Bennett, 1998; Lewis, 2006; Hofstede, 2010; Ting-Toomey and Chung, 2012); and Foreign Language Teaching (Bennett, 1998; Byram, 2000; Ting-Toomey and Chung, 2012; Liddicoat, 2005, 2013). Through a qualitative interpretative methodology taboo words are analysed in nine episodes of the popular situational comedy online series Porta dos Fundos. Seven more frequently used taboo words by Cariocas, namely buceta, cu, caralho, foder, pau, porra and puta, are analysed and interpreted. The semantic and pragmatic use of taboo words demonstrates that they belong to the themes of sexual anatomy, sexual activity, scatology, illicit sex and animal names – although the latter ones are not classified as taboo words. They are compared with Hindi taboo words wherever applicable. The frequent use of taboo words in comedies, satires and other forms of entertainment, as well as in different types of communicative situations, is not, as generally perceived, i.e., a face threatening act (Goffman, 1967) in Portuguese, opposed to what happens in Hindi. The analysis also shows that the Cariocas, as multi-active Brazilians (Lewis, 2006), depending on the pragmatic variables, use taboo words as expressive speech acts to communicate emotions, not always carrying an offensive tone, as when used as interjections. A TbWs didactic proposal is presented for the teachers and students of Brazilian Portuguese as a Foreign Language in India.
