Why do these slang terms become popular? From "delulu" to "67" and then to "hanky panky," why do these strange words always spread within communities? This is not only a linguistic issue but also reflects the vitality of internet culture. Web3 communities are especially keen on creating their own jargon—whether it's trading terminology, market satire, or cultural memes—these expressions foster a sense of belonging among community members. Linguists will tell you that the rapid popularity of new words often stems from three factors: first, they are concise and interesting; second, they can convey emotions or concepts that existing words cannot accurately express; third, enough people are repeatedly using them. In the crypto world, this phenomenon is particularly evident. When a word goes from niche popularity to mainstream awareness, it is backed by a process of community consensus building. This is also why understanding these slang terms, to some extent, is understanding Web3 culture itself.
