Bojihwayangdong buralsongseonsaeng

Bojihwayangdong buralsongseonsaeng is a bilingual pun in Classical Chinese and Korean that is considered to be part of the literature of the Joseon period of Korea. It has historically been used as a source of humour in Korean.

History
When Heo Mok was ordered to attend the academy of the more senior scholar Song Siyeol at Hwayang-dong, he made the journey and was forced to wait for a long time, only to find the appointment had been cancelled. Heo Mok angrily stated "bojihwayangdong buralsongseonsaeng".

Meaning
Interpreted as a Korean reading of 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 have a double meaning of "cunt Hwayang-dong; bollocks teacher Song".
