Stop looking for me, I just want me some quiet alone time. And don't ask who "quiet alone time" is.
Classic Chinese word play. Depending on context, "想" can either mean "wanted to do something" or "miss someone", while "静静" can be either "some quiet alone time" or a typical girl's name. Therefore, this line can also be translated as "Stop looking for me, I miss Jingjing. And don't ask who Jingjing is."
