1. An African-American man, especially one who strives to better the lives of other African-Americans. Jason was a true man—a man who fought tirelessly for his family and his community. He was a soul brother, and he will not be forgotten.

2. A man with whom one shares an intense, intimate, emotional connection. When I got my first acting gig at 18, I was just a scared, cocky kid. But I found a soul brother in Harvey. He took me under his wing, and helped me grow into the kind of man I'd always wanted to be.
