What is 輸打贏要? (Cantonese expression) In this puzzle game I included a Cantonese expression 輸打贏要. and explained it as 'Very bad sportsmanship'
A user asked what it means in the comment section. I replied he can Google it, but the result is in Chinese and most importantly, the term is not explained very clearly.
I post this question so I or someone else can post a better answer than Baidu and in English
The Cantonese expression 輸打贏要 came from Mahjong lingo
'Play Mahjong' in Cantonese is &quot;打麻雀(麻将)'

輸 means 'lose'

輸打 means 'continue to play when losing' (so when the game ends, he will have the chance to promise a gambling debt instead of paying the cash)

贏 means 'win'

贏要 means 'demand payment after every winning hand' (so when the game ends, he will get the cash and not a promise of repaying a gambling debt)


As a former Mahjong player, 輸打贏要 to me refers to the behavior of refusing to pay up after every losing hand when he was losing, insist on continuing to play, until he was winning, and then comes the 贏要 part -- Now he is demanding payment right after every hand.
In short -- Refuse to end the game when losing; eager to end the game when winning'; pick and choose the rules to obey when it benefits you
It is similar to the English expression 'Keep moving the goalposts';
