What is one arm hug?

An one arm hug is a form of hugging where one person wraps one arm around the other person, while the other arm remains by their side. It is also known as the "half hug" or the "one-sided hug". The one arm hug is often used for greetings or showing appreciation or support towards someone. It can also be an indication of a less intimate relationship between two individuals. This type of hug can be comfortable for people who are not comfortable with full body hugging or have physical limitations.
