Much of Gen Z slang follows a specific diffusion pattern. It often originates in Black communities (AAVE) or on 4chan, gets adopted by gay communities, spreads to their social circles, and eventually diffuses into mainstream culture.

Classic regional accents (New York, Boston, Southern) are disappearing in younger generations. However, this isn't creating a uniform sound. Instead, new accent divides are forming along social lines like race, urban vs. rural, and even political affiliation.

With non-native speakers as the majority of English users, the language constantly evolves in diverse ways globally. Efforts to impose a simplified, standard version for business (like "globish") are unlikely to succeed because language is a living system that speakers inherently and creatively adapt, making it impossible to control.

Linguist Anne Kerzan reframes jargon not as a flaw, but as a specialized lexicon for a profession. It provides useful shortcuts and creates a sense of shared identity for insiders. The negative perception arises from being an outsider or when jargon is used to obscure meaning, such as with corporate euphemisms.

Contrary to being a 'lesser' language, slang is arguably richer than standard vocabulary. A standard word often has only a specific referential meaning, whereas a slang term simultaneously communicates the speaker's identity (e.g., Gen Z), their attitude (contempt, affection), and their desired self-perception.

Accents weren't just a byproduct of geographic separation; they likely offered a survival advantage. Natural selection favored the development of accents and our ability to perceive them, as it allowed early humans to quickly identify potential collaborators or conflicts within and between groups.

No language is 'perfect' because its evolution is a trade-off. Speakers tend toward efficiency and simplification (slurring), while hearers require clarity and precision. This constant tug-of-war drives linguistic change, explaining why languages are always in flux.

Because 4chan is anonymous, users must prove their in-group status ('not a normie') solely through language. This intense selection pressure, combined with a lack of other identity signals, made the platform a uniquely potent incubator for new slang and memes.

Linguist Adam Aleksic asserts that roughly 90% of modern internet slang originates from one of two sources: African-American English (AAVE), which spreads because it's seen as cool, or 4chan, which spreads through ironic humor. This reveals the narrow but powerful cultural wellsprings of online language.
