How much of a bro someone with a gnarly flow really is. Usually measured on a scale of 1-10. A bro who lands himself a 10 would often be considered head of dudes in most scenarios requiring some sort of leadership and would be conidered a bro by everyone. The ratio in written form would be whatever number the bro achieves followed by a ":" and then the word flow. Ex. 6:Flow
Bro 1: Dude, that bro has some gnarly locks..
Bro 2: I agree but ive talked to him before and his flow-to-bro ratio is only like 4:flow.
Bro 1: Thats too bad, I thought he would be more of a bro...
