The phrase "rich bitch" is considered an offensive term used to describe a wealthy and entitled woman. It is important to refrain from using derogatory language when referring to anyone, regardless of their financial status or behavior. Instead, it is better to use more neutral and respectful language when describing someone, such as "wealthy woman" or "high-end individual." Alternatively, you may refer to different aspects of their personality, such as "arrogant," "pretentious," or "haughty." These words can better describe someone's behavior without resorting to offensive or derogatory terms. It is important to use language that promotes positivity and respect for others.
