A phrase from the show popular Korean Drama "Crash Landing on You" has earned the ire of North Korean leader Kim Jong-Un, who according to reports saw it as a mockery to his position.

When translated, the phrase which meant "You think you're the general or something?" or "Who died and made you the general?" has now been labeled as a form of mockery to Jong-Un's absolute authority as he is usually referred to as "The General."

However, several reports claim that the crackdown is one of North Korea's target as an attempt to eliminate the cultural influences of South Korea.

According to Daily Mail, a resident from the North Hamgyong area shared that people in North Korea started to popularize lines from famous South Korean dramas so it prompted authorities to start an investigation.

He also added that another reason why the Law enforcement authorities conducted such investigation, it is because of the usage of South Korean-style of speech in criticizing the Supreme Leader.

South Korean slang is banned in the North.

According to Express UK, the resident from Hamgyong also mentioned that the Judicial officers are now using their crackdown capabilities to determine how the media of South Korea entered the Hermit state.

The phrase now becomes a common part of North Korea's speech due to the start of its popularity late of last year, since then according to the resident when people are trying to point out someone inexperienced or young and thinks they are above themselves they use the said the phrase relating to the general, which for him mocks Jong-Un.

While a resident in South Pyongyang shared that they use the phrase whenever they are mocking someone for being arrogant and stuck-up.

According to the resident, in the past, they held the utmost respect for the highest dignity, but not anymore as people use the South Korean phrases more than using the terminology 'highest dignity' on a daily basis.
