Song: Life is a Bi... | 인생은 나쁜X
Artist: BIBI | 비비

It tries to fuck up my liver, but... (내 간을 엿 바꿔 먹으려 하지만) - This is an idiomatic expression that translates more literally to "It (life) tries to exchange my liver for yeot." Yeot (엿) is a traditional Korean candy. This idiom "to exchange ____ for yeot" comes from a time period after the Korean War when the nation was extremely poor. Most children did not have money for candy, but yeot vendors would allegedly urge them to bring scrap metal or household goods in exchange for pieces of yeot. These children were obviously being duped into an unfair trade. In modern times, the phrase "exchange __ for yeot" has become a vulgar expression with the word "yeot" being co-opted as a swear. (Maybe you are familiar with the Korean phrase "eat yeot" which is the equivalent of "eat shit" or "fxck you") For example, the question "Did you exchange my money for yeot?" (내 돈 엿 바꿔 먹었어?) is better understood as "What the fxck did you do with my money?"
