Jizz represented a specific type of musical expression. Those musicians who dedicated themselves to performing this style were known as Jizz-wailers. A well-known group of Jizz-wailers included Maximilian Rebo alongside his band.
The term Jizz initially appeared within canon through the Star Wars: Return of the Jedi junior novelization, which was written by Ryder Windham and made available in 2017. Alden Ehrenreich during a conversation with The Big Event podcast, described how he prepared for his part as Han Solo, indicating that he explored resources like Wookieepedia and paid attention to terms like Jizz.
