Bojihwayangdong buralsongseonsaeng
When Heo Mok was ordered to attend the academy of the more senior scholar Song Siyeol at Hwayang-dong, he made the journey. Once he got there, he was forced to wait for a long time. Then he found out the appointment had been cancelled. Heo Mok angrily stated "bojihwayangdong buralsongseonsaeng". In Classical Chinese, the statement means "Walked to Hwayang-dong; did not see teacher Song", but in native Korean, boji () refers to "female genitals", while bural () means "testicles", making the expression additionally mean "cunt Hwayang-dong; testicles teacher Song".
