Badmouthing someone or something can lead to negative consequences. It's important to choose words carefully, as they have the power to affect people's opinions and attitudes. There are several synonyms for "badmouths" that convey a similar meaning but with varying degrees of intensity. Some examples include criticizing, denigrating, maligning, derogating, disparaging, and vilifying. While these words may be necessary in certain situations, it's important to consider the impact they may have on others and to practice thoughtful communication. Instead of badmouthing, we can choose to provide constructive criticism, offer feedback, or simply refrain from saying anything negative at all.
