Gen Z & Youth Slang

TikTok talk, zoomer vocabulary, and the language of the young

Introduction

Every generation develops its own vocabulary, but Gen Z has accelerated this process through social media. Terms can go from obscure to mainstream in days, creating a fast-evolving linguistic landscape that leaves older generations bemused.

This isn't just about being trendy—Gen Z slang often provides more precise ways to describe modern experiences. "Main character energy," "living rent-free in my head," and "that's giving" capture nuances that older phrases simply don't. The vocabulary reflects a generation shaped by the internet.

This chapter captures the Gen Z expressions that have achieved staying power—the slang that's moved beyond TikTok into everyday speech. Some of these terms will date quickly, but many have already become part of how we all talk about the world.
