The type of communication you are referring to is often categorized as nonverbal communication. Nonverbal communication includes gestures, body language, facial expressions, eye contact, and tone of voice.
When gestures and tone of voice convey a threatening message, it can be considered a form of aggressive or hostile nonverbal communication. For example, raised voices, aggressive gestures, or a tense posture can intimidate the other person and create a perceived sense of threat, even if the words spoken are not explicitly aggressive.
It's important to be aware of how nonverbal cues can affect interpersonal interactions, as they play a significant role in how messages are interpreted and the overall dynamics of the conversation.
