Grime music originated in East London in the 1990s and has grown tremendously in popularity over the past 20 years. A young grime artist named J Hus has achieved great success through several hit songs and playlists that his fans enjoy. However, his success caused rivalry with another young grime rapper, Kojo Funds. Kojo Funds stabbed J Hus in the leg while they were supposed to collaborate, due to jealousy over J Hus's popularity. In response, J Hus released a "diss track" called "Delajore" in December 2015 to insult Kojo Funds. After this, J Hus knew not to trust others and to keep a low profile for a time before continuing his successful career.
