The Paishacha marriage (Sanskrit: पैशाचविवह्, romanized: Paiśāchavivāha) is a non-righteous form of marriage described in Hindu literature.
When a man stealthily rapes a woman who is asleep, intoxicated, or mentally challenged, it regarded to be a marriage, though only to preserve the honour of the woman.
[1] This is condemned in the Manusmriti as a sinful act.
[2] In modern times, this is classified as a form of date rape, and is a crime in most countries.
