The 'Bye Bye Man Poster Parodies' stem from the promotional material for the 2017 horror film The Bye Bye Man, which featured a hooded figure and the ominous warning, 'Don't think it, don't say it.' Almost immediately, the internet latched onto the generic nature of the title and the repetitive tagline, leading to a wave of ironic edits. The most famous iteration, 'The Pee Pee Poo Poo Man,' transformed the gritty horror aesthetic into a playground for surreal and juvenile humor. Today, the template is used to mock anything from intrusive thoughts and catchy songs to niche internet drama, proving that even the most serious horror marketing can become a comedic staple if the name is just silly enough.
