Get soy sauce
From China Digital Space
dǎ jiàngyóu 打酱油
None of my business. Conveys the sense of spectating or reserving comment.
In 2008, Guangzhou Television interviewed a local man about the Edison Chen photo scandal. The man answered, "What the fuck does it have to do with me? I was just out buying soy sauce." The response became a meme, applicable to any context, such as to express one's lack of interest in the World Cup:
Lulu318 (@璐璐318): The World Cup has started. Many people are immensely excited. I am just here to get soy sauce. (June 12, 2014)
Dǎ 打 means "hit" or "get." Before soy sauce was sold in individual bottles, customers would bring an empty vessel to the store, which they would fill with soy sauce from a spigot.
