Patrons stand and dance inside the Boho nightclub during Detty December in Lagos on December 15, 2025. Detty December refers to the lively Lagos tradition where December is packed with nonstop parties, concerts, nightlife, and cultural events, fuelled by returning diaspora Nigerians and heightened local celebration. The city becomes especially vibrant and crowded as entertainment and tourism peak. The spelling detty comes from Nigerian Pidgin English, where it is a playful version of dirty that implies excess, intensity, and carefree fun. (Photo by OLYMPIA DE MAISMONT / AFP)
