A representation of a creature (typically a snake or dragon) forming a continuous circle or loop by biting (or seemingly eating) its own tail. The ouroboros is an ancient symbol, found in Ancient Egyptian and Ancient Greek cultures, as well as medieval alchemy. The Ouroboros can represent infinity, or the endless cycle of life and death.
In furry art, a long (likely split form, feral or semi-anthro) character may form an "ouroboros" by performing autofellatio or by inserting their snout or head into their vagina or anus. Avoid tagging ouroboros as auto vore, unless other content in the post prompts it.
