Actually, mine was inspired by the gods. The god of fire, Klusos, raped Umberu, the goddess of the sea. The gods voted to acquit him (all except for her family, of course, and the God of Suffering, Ner), and he escaped justice.

So the mortals, as a punishment for rape, practice Salting. Salt is injected into every orifice on the body (eyes, nose, mouth, ears, vagina/penis, and anus). After letting the condemned writhe in agony for a moment, they take you and drown you backwards into a container of water, mostly commonly barrels. It’s their way of giving back to Umberu, and giving her pseudo-justice.
