bros or bust
A mere phrase that defines something that is almost indescribable in English words. It is beyond brohood or broship. It is a brosphere. An undying, indestructible, omnipotent bond between bros that is incomprehensible to outsiders and lasts beyond biological death.
Tim: It's bros or bust.
Mark: To death and beyond, bro.
Mark: To death and beyond, bro.
