装模作样绿茶婊外猛内柔女汉子

This describes someone who appears hypocritical (putting up a pretentious show), with both fierce external demeanor yet a softer side; '绿茶婊' specifically references the type stereotypically known as pretending to be demure and innocent while harboring devious thoughts, while a 女汉子 is a woman who acts like what’s considered traditionally male, strong willed. This name could carry pejorative or self-deprecating meaning depending on context.
