mâi jú zî 买橘子

mâi jú zî (买橘子) means "buying oranges". The meaning of the word as a cyber language is derived from a description of Zhu Ziqing's prose "back" from Chinese junior high school textbooks.

"I said, 'Dad, you can go.' He looked out of the train and said, 'I'll buy some oranges.' You stay here, don't move. " I think there are several sales people waiting for customers outside the fence over the platform. Father walk over to the platform, cross the railway and jump down and climb up."

So on the Internet, the term "buying oranges" is extended to imply that "I am your father" means to take advantage of others.

The term usually appears in the reply of popular comment of posts, meaning that praising someone's comments is very impressive and savage.
