Guy to chill with. long-time friend.

Contrary to popular belief, homeboy along with homie were both created by Chicano aka Mexican American Pachucos from the word "Hombre" which is spanish for "man". It all derived from the slang they used known as "Calo".

In the California Prison system a "Homeboy" is someone from the same race and county you are from whom you are on good terms. Your "Home" town etc

home boy to a girl is a great friend who has her back and is real too the end

The term "homeboy" derrives from "homie", and each of those terms have been shortened down overtime as "homes", or sometimes spelled "holmes". The term was started by Mexican-Americans living in the barrios of Los Angeles, most commonly said in East Los Angeles. The term refers to friends/companions living in the same neigborhood as eachother. Which is why "HOME" is started before boy, thus creating "homeboy".
