This article analyzes the semiotic representations of gender through the language practices of Cameroonian youth observed in Tu Know Ma Life (You know my life), a YouTube series popular among the French Cameroonian diaspora that follows the daily life of nine young middle- and upper-class Cameroonian immigrants (five women and four men) living in Paris. This series is regarded by its audience as an authentic representation of Cameroonian identity, partly due to its remarkable use of Francanglais, a hybrid youth slang spoken in Cameroon. I analyze how the mediatized representation of Francanglais practices in the first season of the YouTube series contributes to the linguistic construction of gender differentiations. I argue that through the highly gendered use of Francanglais and French by women and men, the series reproduces hegemonic gender ideologies while reinforcing the ideological association between Francanglais and hegemonic heterosexual masculinity.
