Origin Story
King Yeonsangun (r. 1494–1506) was so fond of song and dance that in the eleventh year of his reign (1505) he ordered every district in the kingdom to supply performing entertainers called unpyeong (運平). The number gathered swelled to some ten thousand, and from among them the most beautiful were selected and summoned into the palace, where they were called heungcheong (興淸) — a name meaning "to raise up a pure and clear spirit." Yet the king sank into luxury and dissipation alongside these heungcheong, until he was finally deposed in the 1506 coup that restored King Jungjong. The people said the king had been ruined because of the heungcheong, and mockingly attached the character mang (亡, "to ruin") to the name, making heungcheong-mangcheong (興淸亡淸). The downfall of a single tyrant froze, intact, into one word — and the elegantly named court entertainers became shorthand for every kind of reckless, high-spirited squandering.
A king's indulgence and ruin are preserved whole inside a single word. A name that once meant "to raise up clarity" became, by a twist of history, the very byword for the most wasteful extravagance.

Memory Hook
The entertainers heungcheong (興淸) + mang (亡, "ruin") → "ruined because of the heungcheong" → squandering and falling, just like King Yeonsangun.
"A name meaning "to raise up clarity" became, along with one tyrant, the very byword for the most wasteful excess."
