Two popular music genres that popularized nouchi in Côte d'Ivoire and then France are "Zouglou" (1990s) and "Coupé-Décalé" (2000-2010s). Both are past their primes but it's interesting to watch now the diffusion process into the French culture. In 2019, a few nouchi words were added to the Larousse dictionary: https://www.france24.com/fr/20190601cote-ivoire-nouchi-argot...
