Xiaobai, move a small stool and give you science about what meme is.

The concept of "MEME", which is defined as a unit of cultural transmission, is similar to genes in biological heredity. MEME can be a melody, an idea, a style of clothing, a linguistic habit, a technique, or any other phenomenon of cultural transmission. They replicate themselves in human culture by mimicking from one person to another. The success and survival of MEMEs, like genes, depend on their replication precision, persistence, and their "attraction" or utility to the host.

In more easy-to-understand terms, MEME can be a meme, a joke, a meme, etc., a subculture formed after widespread dissemination. The MEME coin is a way to value this subculture.
