The 'Skilometer' meme is a clever wordplay that merges the imagery of a skeleton with the metric unit of measurement, the kilometer. Often surfacing during the 'Spooktober' season, this meme typically features a skeleton in a pose of either speed, measurement, or existential dread. It gained traction as a subversion of the 'What the hell is a kilometer?' meme format, where the skeleton represents a more European or scientifically-minded alternative to the typical American measurement memes. It is widely used to mock height requirements on dating apps or to simply celebrate the absurdity of pun-based humor within the skeleton meme subculture.
