The Brief: For the month of October, Reddit fills up with skeleton memes including inside jokes about trumpet-playing, calcium-obsessed skeletons that say "doot doot."

DEEP DIVE
As a part of Spooktober celebrations, memes featuring calcium-craving-skeletons, trumpet-playing-skeletons, and other spooky themes haunt the internet. These spoopy memes are popular on Reddit and on the Dank Memes subreddit in particular.
The skull trumpet or skeleton trumpet meme originated from a video of a cartoon skeleton playing the trumpet. From there, catchy remixes of the videos and various Halloween season memes surfaced and proliferated. “Doot doot” is often referenced in these memes as an onomatopoeia of the sound of a trumpet. Many memes joke about how skeletons love calcium because it helps them build strong bones.
Annually, on October 1st, Reddit and the rest of the internet experience a surge in Halloween memes and related content. Reddit’s brand of Halloween festivities typically focuses on skeletons, doot dooting, and references to Reddit’s unwavering devotion to celebrating spooktober.
