Originally derived from two ancient celtic words "Bran", and "um". Meaning large testicles. In the middle ages, the word "Branum" was used to describe enviable bravery and loyalty towards ones "true" family. In modern times, the word Branum has been known to drive wimpy little "I can't cut the apron strings" momma's babies into a typical narcissistic rage. Often to the point that they display the projection of their own faults in definitions onto others as they are known to do.
The best example is: "It takes a real man to be BRANUM"...
