also: ふりてん
noun
furiten; temporary restriction on winning by discard
In mahjong, a state where a player cannot win on a discarded tile because one of their own waits has already been discarded, or they previously declined a winning tile. The restriction is lifted when the player draws a tile or changes their hand.
リーチ後にフリテンになってしまった。
I ended up in furiten after declaring riichi.
フリテンだとロンであがれない。
When you're in furiten, you can't win by ron.
Abbreviation of 振り (furi, 'discard') + 聴牌 (tenpai, 'waiting hand'), referring to a tenpai state where a winning tile has been discarded. The exact derivation is uncertain, but it is a well-established mahjong term.
