What is "heyoka"

The heyoka (heyókȟa, also spelled "haokah," "heyokha") is a kind of sacred clown in the culture of the Lakota people of the Great Plains of North America. The heyoka is a contrarian, jester, and satirist, who speaks, moves and reacts in an opposite fashion to the people around them. Only those having visions of the thunder beings of the west, the Wakíŋyaŋ, and who are recognized as such by the community, can take on the ceremonial role of the heyoka.

The Lakota medicine man, Black Elk, described himself as a heyoka, saying he had been visited as a child by the thunder beings. ( Thunderbirds).
