Waka has said several times that's he's not from Atlanta, he's from Clayton County. I don't expect people who don't live in Atlanta to realize the difference but Riverdale nikkas are different breed.
But if you want to get technical, 80% of the rappers that claim "Atlanta" lived in neighboring cities like College Park (Pastor Troy, Ludacris), Decatur or East Point (Outkast). No one ever calls they ass out on it because we're not petty like that. Migos claiming they're from Atlanta when they grew up 35 minutes away in the suburbs and went to high school with more white people than black is what i find hilarious. Some of these nikkas probably only stepped foot in Atlanta to go to Lennox Mall or Atlantic station before they blew up. Don't be fooled. That fakkit Young Thug a straight up Cleveland Avenue boy though.
