S M F otherwise known as Sergio Mora Fan, but to me it means Smart, Motivated, Funny. He is a man that is extremely loyal, and is know in many boxing forums, to defend the Latin Snake to the very end. Even when fans of Peter Manfredo Jr get vulgar, and make personal attacks on him, he just lets it roll off his back. He is a man that is very selective in who he befriends, but once he does, he is the best friend you could ever want. He is giving, big-hearted, helpful, kind, creative, humorous, and so much more. He is, the best part of my heart.
I believe in fate, and just when I needed it, God brought S M F into my life.
