The Wicker Man was a large wicker statue of a human used by the ancient Druids (priests of Celtic paganism) for human sacrifice by burning it in effigy, according to Julius Caesar in his Commentarii de Bello Gallico (Commentary on the Gallic War).
In modern times, the figure has been adopted for festivals as part of some neopagan-themed ceremonies, without the human sacrifice element.
"A giant man made of wicker used in human sacrifices by Druids of ancient Celtic descent. The sacrifice was held inside, then the wicker man would be set ablaze. Some tales describe passersby stumbling across the remains, wondering how they got burned."

Its description makes a reference to the 2006 remake of The Wicker Man, starring Nicholas Cage. There is a scene where Cage's character discovers a burned doll and demands to know "how'd it get burned?" in an over-reactionary fashion, making the scene popular for parody and remixes.
