Rich second-generation kids sometimes like to flash their wealth by spending lavishly.
Tips
history
From Wu Xiangzhi's Tang poem 《少年行》: 一掷千金浑是胆，家无四壁不知贫 — a reckless youth gambles away a thousand gold in one toss, too proud to notice his empty house. The 'gambling throw' sense still tints the modern meaning.
usage
Often describes lavish spending or gambling; tone ranges from admiring ('bold') to critical ('reckless') depending on context. Contrast with 精打细算 (careful, thrifty) and 省吃俭用 (frugal living).
