The Raiders chant comes from Raider Nation, the fan base of the franchise founded in Oakland in 1960 and now based in Las Vegas after moving in 2020. Supporters in Silver and Black have used the slow, repeated call at home and away stadiums for decades, including famously loud games at Mile High. It spread online as short clips of crowd cheering were shared by fans during NFL seasons, turning a live stadium ritual into a reusable sound for edits, memes and game day posts whenever the team is mentioned.
