2025 slang

2025 was the year a few specific words hit critical mass: demure, brat, mob wife, AI slop, and vibe coding all crossed from subculture to mainstream within twelve months. It was also the year algospeak fully shaped how creators talked online, and the year corporate slang absorbed AI vocabulary at speed.

This is a snapshot of what landed. Some of these terms will be permanent additions to English; some are already showing wear. We'll mark the ones that fade as 2026 progresses.
