Sweet Home Alabama was released by Lynyrd Skynyrd in 1974 and became one of Southern rock's most recognisable songs. Online, its title alone turned into shorthand for jokes about incest, playing on a long-running stereotype about rural Alabama. Short instrumental covers, including ukulele versions shared on YouTube, gave editors a clean, copyright-light punchline they could drop into reaction videos. The 'me after realizing' format paired the tune with dawning horror captions, helping it spread across meme pages and short-form video as an instant signal of a forbidden family twist.
