The 'Cumbox' meme originated from a notorious 2012 Reddit post in the 'AskReddit' subreddit where a user shared photographs of a cardboard box they had used for years instead of traditional disposal methods. The image quickly became one of the most famous examples of 'internet gross-out' culture, earning a permanent spot in the Reddit 'Museum of Filth.' In meme culture, the Cumbox is used to represent the horrifying or unhygienic depths of the anonymous internet. It is frequently referenced when discussing legendary Reddit threads or when someone wants to shock a newcomer to internet lore with a piece of unshakeable, albeit disgusting, history.
