1. One's male significant other. Where's your man? Is he coming to the party tonight? I'm so glad I got to meet your man on Saturday! He seems like such a nice guy.

2. A man who can complete or help with a task or job because he is skilled in that particular area. I used to play basketball in college, so if you need any tips, I'm your man! Todd's a great mechanic—if your car breaks down, he's your man.
