흥청망청

Etymology
The first element is traditionally taken to be, a group of thousands of courtesans who were gathered in 1504 from all over the country by the infamously hedonistic and tyrannical king , who was later deposed for his crimes. The connection between the first syllable of the ideophone and the Chinese character is certain, although the connection to the specific monarch is not unassailable.

The ideophone is a rhyming reduplication involving the Chinese character, establishing a contrast with the first character. Thus the ideophone sets up a contrast between the decadent flourishing of the present day, and the future ruin that it will inevitably lead to.

Ideophone

 * 1)  decadently, wastefully
