Tooka, was a nickname referring to Shondale "Tooka" Gregory, a young man from Chicago who was tragically killed in 2011. He was associated with a gang called the Gangster Disciples. The term "Tooka" became significant within the context of Chicago drill music, as several drill artists from rival gangs made references to Tooka in their lyrics. It's important to note that drill music often involves references to local gang activity and can be controversial due to its explicit content and the real-life feuds it may reflect. However, please keep in mind that my information might not be up-to-date, so there may have been further developments in the subject since then.
