The Tim Walz Horse Semen Story is a viral internet hoax that emerged in 2024, circulating primarily on social media platforms like X (formerly Twitter). The claim was entirely fabricated, designed to mimic the absurd and 'weird' political smears that characterize modern digital discourse. Fact-checkers across the globe quickly identified the story as a total invention with no basis in reality. Despite being debunked, the narrative persisted as a meme used to mock the speed at which misinformation spreads or to satirize the increasingly bizarre nature of partisan attacks. It serves as a prominent example of how shock-value humor and disinformation often intersect in the viral landscape of election cycles.
