(Similar to the concept of Grown Man Strength
) When an individual develops a passionate love for another individual that is far more intricate and powerful than the typical relationship stage. Grown Man Love is impossible to imitate or fake and therefore takes an exponential amount of emotional experience and passion to achieve. It is more than just saying, "I love you". Grown Man love involves wanting to spend as much time as possible with your significant other and realizing that they mean the world to you. Also, Grown Man Love is unlike the love you experience with your direct and extended family or even with your closest friends; it's a stronger brand of love that one cannot fully understand he/she experiences it.
"A and B's relationship is somethin', man. They're like, lovers AND best friends!"
"damn, that must be some Grown Man Love
