Definition
Smiling broadly or grinning from ear to ear, with a wide, cheerful mouth resembling the character on a four-ten-thousand mahjong tile.
How it's used
This idiom draws a visual comparison to the character 四 on the mahjong tile for forty thousand, which features a wide, open design resembling a broad smile. It is used exclusively to describe a person's facial expression when they are beaming with joy or laughter. It carries a slightly playful or exaggerated tone, making it perfect for describing someone who is unusually happy or perhaps gloating about good news.

Common mistake
Do not use this to describe a polite or subtle smile, as it specifically refers to a wide, toothy, or ear to ear grin. It is also not used to describe the smile itself as an object, but rather the person who is wearing that expression.
