The mass of people who know nothing of the truth. Content to simply eat melon.
A Chinese Internet slang term used to describe oneself or a faction you identify with, showing a sort of listlessness or nonchalance to certain intricacies; can be more or less repulsive when one means to do nothing but to be a mere spectator. And sometimes, the phrase has a sense of being opposite to the authorities, to the effect of satirizing their trying to hide or distort something that they do not wish to have disclosed, in all probability, a home truth.
