Hahhaha, no I'm kidding.
According to Merriam-Webster online "homie" is an abbreviation for "homeboy". The definition of "homeboy" is given as such:
Main Entry: home-boy
1 : a boy or man from one's neighborhood, hometown, or region
2 : a fellow member of a youth gang
3 : an inner-city youth
But (1) isn't quite accurate in this case, and I doubt (2) or (3) apply to you. Unless you have some secret identity you would like to reveal to the general membership?
It just means "you're cool with me". It's not just a shared physical or criminal affiliation. Ever since that 'member analyses' forum (which strangely seems to have disappeared?) where I volunteered to be your finger-wagging right hand gal (the of death!) I have known I can rely on you as my tasteful rule-abiding British Moderateur.
Hence, you are my homie.
It's a playful phrase...like when people say, 'Jesus is my homie'...
(Hey giving lessons on American colloquial is fun!)
Which brings me to:
Edahn's picking on me!
(Ha Edahn, I gotcha now! )
