Who was the first youngest rapper?

The title of the youngest rapper is often attributed to Lil' Poopy, who gained fame at the age of 9 for his explicit lyrics and performances. However, other young artists like DJ Jazzy Jeff & The Fresh Prince's Will Smith and various child performers have also made significant early impacts in hip-hop. Ultimately, the definition of "youngest" can vary based on criteria, including age at release or prominence in the industry.
