ungentlemanly

An ungentlemanly behavior or action is not very respectful and often considered rude. It's something that someone who is supposed to behave with kindness and politeness might do.

When people talk about being ungentlemanly, they're usually referring to a situation where someone in a position of authority, such as a boss, teacher, or even a parent, has acted disrespectfully towards others. This can be anything from yelling at someone for no reason, to taking credit for their work, or to treating someone with contempt. Sometimes, people might accuse someone of being ungentlemanly if they're acting selfishly or hurting others' feelings on purpose.

As the word often carries a slightly old-fashioned tone, it's mostly used in more formal situations, like writing or speaking about serious issues, but it can also be heard in everyday conversations. It's not as commonly used as other words that describe bad behavior, like rude or mean-spirited.
