An individual who you have been destined to become best bros with. It is similar to that of a soul mate but to a higher degree and a more genuine manner.
Bubba: You are the perfect bro for me. We are similar in every way possible.

Forrest: Yeah, you're my soul bro.

The Soul Bro is that one and only best friend for you. They are the other half to your life of friendship.

The Soul Bro or "Soulbro" is the one and only best male friend for you, one that you can feel in your heart and soul that they have been destined to become more than your best friend. They are the other half of your life of friendship and they both have complete trust of each other. They are like the opposite gender soulmate but to a higher extent. Relationship can be platonic, and can include sexual activity
Like soulmates, except between two males (hence Soul Bros) such as brothers or close friends, aka "bros."

- "Your my Soulbro, I can trust you completely, and we are always thinking about each other. I love you bro."

- "I love you too man, we are always there for each other no matter what because your my soulbro"
