This is a combination of "Scro", (a playoff of the words
brother and scrotum) and "homey"
short for homeboy, someone you grew up with, someone you
trust and admire.
My big
brother and I are only two years apart in age, he is my older sibling, but we are
tight and his nick name of bro has evolved throughout the years to scro, and now scromie. Basically, I am referring to my bro as a ball
sack which also is my Homeboy!
