In AustralianAboriginal mythology (specifically: Murngin), Bamapana is a trickster hero who causes discord. He is obscene and profane and once committed incest, thus breaking a strict taboo. The Aborigines of Australia have a polytheistic, animistic religion. ... In the study of mythology, folklore and religion, a trickster is a god, goddess, spirit, human hero or anthropomorphic animal who breaks the rules of the gods or nature, sometimes maliciously (for example, Loki) but usually with ultimately positive effects. ... Incest is the sexual activity or marriage between very close family members (and sometimes friends in some societies). ... A taboo is a strong social prohibition (or ban) relating to any area of human activity or social custom declared as sacred and forbidden; breaking of the taboo is usually considered objectionable or abhorrent by society. ...
Bamapana is obscene, he's causes discord (and laughter, another kind of discord?), he flouts conventions, specifically the taboo against incest...
So I guess (and here I am guessing) any trickster figure here would be at once an entertainment and a horror or source of uncertainty, in that he embodied that which the convention said was taboo.
But Bamapana is the only trickster name I know of, so the trickster figure might be less widespread that I'm guessing.
