mate.
A friend or a familiar way to address someone. It can sound warm, neutral, sarcastic, or confrontational depending on delivery.
What does mate mean?
A mate is a friend or companion. “My mates are coming over” is an ordinary informal description of a friend group. As direct address, mate can also be used with someone you do not know well: “Cheers, mate” may simply be friendly thanks.
Tone changes a great deal. A clipped “listen, mate” can introduce a warning or disagreement. The word alone does not prove friendship or hostility. It also has unrelated uses in compounds such as classmate and technical or biological contexts. A US listener may understand the friendly meaning without using it naturally themselves.

The right word.
The right moment.
Use it in a familiar conversational setting where it fits your natural speech and the relationship. Direct address is sensitive to tone and local habit.
Avoid assuming it is always friendly or forcing it into a formal introduction. A stranger using mate is not necessarily claiming personal closeness.
Not quite the same as…

Mate can simply mean friend. It does not automatically mean a romantic partner or a biological mating relationship.
