When someone mutters under their breath you may be a little taken aback because it can be rude, passive-aggressive, and hostile behaviour. Maybe the person doesn’t like what you said, and instead of being an adult and confronting you about it, they walk away and then mutter complaints under their breath.
Often people think they get away with making snide comments under their breath without being called out for their shitty behaviour.
The person you are dealing with may not have the courage to talk to you openly about what is bothering them. When you ask them directly what they said, they reply, “nothing,” and won’t repeat what they muttered back to you.

Jeannie’s husband was always muttering under his breath, and it became so extreme that it was a deal-breaker for her. She didn’t want to have him near her friends because of his uncouth behaviour. She spoke to him directly and told him that it was a deal-breaker for her and he needed to stop doing it immediately.
Her husband continued to complain under his breath but now she called him out every time. Jeannie would say, “What was that you just said to me? I didn’t catch it? It would be helpful if you could speak clearly to me.”
Jeannie kept calling her husband out on his bad behaviour , every time he did it she would say it sounded like he had duct tape over his mouth. Because he knew that he was going to get called out every time he muttered under his breath, he eventually stopped doing it.
