What does heiyigu mean?

Ai Yigu means "Oh my God! Oh my god!"

Hey Yigu, an Internet modal particle, is the transliteration of the Korean "", which is equivalent to the "Hey" we often say. Hei Yigu became popular because of the Korean drama "Reply 1988". Hei Yigu often appeared in the drama, and his pronunciation was very strong, which left a profound impact on people.

Extended information:

President Jin in "Reply 1988" is a cold joke and nonsensical person. Only Deshan can understand him. Every time I see the nonsensical way of greeting between President Kim and Deok-sun, I find it very funny. "Hey Yi Gu, President Cheng, Yi Yi Gu, President Jin. I'm so happy to see you, so happy...". Also because Deshan was willing to pick up on President Kim’s jokes, President Jin would always say to Deshan with emotion: "Deshan, you are the best to me."

Although President Kim is in the drama, he always likes to make nonsense and always likes to linger on the edge of committing suicide. However, he really brought us a lot of joy, and his love and daily life with Ms. Leopard were also very touching.
