When something is said or done that is deemed inappropriate, vulgar, or offensive, it's often referred to as being "in bad taste." However, there are several other synonyms that can be used in place of this phrase. For instance, one can say that something is "uncouth," "crass," "tactless," "impolite," "insensitive," or "off-putting." Similarly, one can use the words "vulgar," "indecent," or "offensive" to describe something that is in poor taste. Ultimately, whichever synonym you choose to use will depend on the context and severity of the situation. Regardless, it's important to choose your words carefully and be mindful of others' feelings.
