Spooktober is an internet phenomenon that takes place every October, where social media is flooded with skeleton-themed memes, often accompanied by the catchphrase 'Doot Doot.' Rooted in the 'Skull Trumpet' video from the mid-90s, the trend evolved on platforms like Reddit and Tumblr to celebrate the approach of Halloween with a mix of irony and genuine enthusiasm. It usually begins as early as September (often called 'Spooktober Eve') and features skeletons gaining strength through 'calcium.' The meme is a staple of internet culture, symbolizing the collective excitement for spooky season through recurring imagery of skeletons, dancing ghouls, and trumpets.
