Finding synonyms for the term "ugly man" can be a tricky task as it can be considered subjective and offensive. However, some alternatives could include "unattractive man", "unappealing man", "homely man", "plain-looking man", or "less-than-captivating man." It's important to note that these terms shouldn't be used to insult individuals or make them feel uncomfortable about their appearance. Everyone has unique features that make them beautiful in their own way. It's important to focus on a person's character rather than just physical appearance. When in doubt, it's best to avoid using negative adjectives to describe someone's appearance and instead find positive ways to describe their qualities.
