alpha bro 

The leader of a pack of bros; inspires the worship of subordinate bros through being slightly more articulate and much more aggressive, and having both a higher alcohol tolerance and better luck with the bro hoes.

At a frat party:

Rachel: What's the matter with all the bros tonight? They seem subdued.

Sarah: Yeah, Vinny's not here. They're totally lost without their alpha bro.

Soul bro 

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"
