In most variants of Mahjong with restrictions on when a player can complete their hand off a discarded tile (especially Japanese Mahjong with furiten), the English rules refer to the situation as a "sacred discard". This confuses me, because the kanji etymology for furiten (振聴) seems to mean something more like "thrown-away tenpai" (as in 振り聴牌, furi-tenpai), and no other variant that I know of has a specific word for it like Japanese does.
Where did the term "sacred discard" come from, in that case? Was it just a culturally interpretive term invented by English-speaking players? Or does this term actually exist in some variant?
