What is "boss is dead again" in jojo?

The BOSS in JOJO refers to the boss Diablo in the fifth movie. Finally, he was defeated by the protagonist's body double gold experience requiem. The effect of gold's requiem is probably that he can never reach the truth. As a result, the boss is always in death and can't reach "real death", so he wakes up and experiences the infinite cycle of death again, and each death experience is different, such as being killed by a car, drowned by a tramp and stabbed to death by a tramp. . . So the boss died again. . . My boss died several times while I was typing. . . You can understand that boss is crossing infinitely, but his crossing will only make him die in a short time, but he can't really die. He will wake up after each death and face different ways of death again. . .
