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.

Bottom line
By the end of 2026 we'll know which of these became permanent vocabulary and which became dated markers of "that one year." Most slang doesn't survive a decade — see the lifecycle piece for why.
FAQ
What was the most viral slang of 2025?+
Demure (post-Jools Lebron), brat (extended into 2025), mob wife, AI slop, vibe coding, canon event (still going), and clanker as a satirical anti-AI term. Aura farming emerged later in the year.
What 2025 slang will last?+
Too early to call. Best bets: AI slop, vibe coding, canon event, and aura (as a points concept). Demure and mob wife may already be fading by mid-2026.
Where did 2025 slang come from?+
TikTok (demure, mob wife), AI Twitter (AI slop, vibe coding, clanker), Spider-Verse (canon event still spreading), and brat marketing's long tail. Algospeak fully matured as a creator-driven dialect.
What 2025 slang is showing wear already?+
Mob wife had a six-month aesthetic window then mostly stopped. Demure peaked in summer 2024 and has been on a slow downward slide. Brat is still alive but the 'summer' has firmly passed.
