>>19698506For a ninja, their "ninja way" is the code or philosophy that they follow to live life as a ninja. Bae is not a ninja, so here she is referring to her philosophy on life in general.
YOLO stands for "you only live once" and is used to justify taking the risky but rewarding option when making a decision. If you only live once, it is better to live life to the fullest, even if it means taking risks.
Putting these together, "YOLO is my ninja way" means that Bae lives her life by choosing the risky path forward over the safe way out. It is a weeby way of saying that she lives life on the edge.
