A "below-the-belt comment" is an insult or criticism that is considered unfair or inappropriate because it targets personal characteristics or private matters, rather than sticking to the issues at hand. It's a type of attack that feels invasive and leaves people feeling vulnerable and hurt. If you're looking for alternative ways to describe this type of negative language, consider terms like low blow, cheap shot, or uncalled for remark. Other options include mean-spirited comment, hurtful statement, inappropriate statement, or personal attack. Regardless of the exact words used, it's important to recognize when someone is crossing a line and to stand up for yourself or others in the face of such behavior.
