Bloody Bones

[2] Samuel Johnson in his Dictionary of the English Language (first published in 1755) defined "Rawhead" as "the name of a spectre, mentioned to fright children".

If you were heroic enough to peep through a crack you would get a glimpse of the dreadful, crouching creature, with blood running down his face, seated waiting on a pile of raw bones that had belonged to children who told lies or said bad words.

[8] In the Southern United States, Rawhead and Bloody Bones are sometimes regarded as two individual creatures or two separate parts of the same monster.

One is a skull stripped of skin that bites its victims (Rawhead) and its companion is a dancing headless skeleton (Bloody Bones).

In the start of episode 12 in the first season (2005) of TV series Supernatural, the lead characters, Sam and Dean, are fighting a rawhead.
