September 2025 was a pivotal month for internet culture. Two viral phenomena exploded simultaneously on TikTok: the "We Are Charlie Kirk" AI-generated song and the FAHHHH sound effect by Taileons. While they emerged from completely different corners of the internet, they collided in the same feeds, the same edits, and the same cultural moment — creating what many consider the defining meme era of late 2025.
The "We Are Charlie Kirk" Phenomenon
What Happened
On September 10, 2025, American right-wing media figure Charlie Kirk was assassinated. Six days later, on September 16, 2025, a creator named Spalexma released an AI-generated tribute song titled "We Are Charlie Kirk" as part of an album called "Charlie Kirk Forever Alive."
The Viral Explosion
The song spread across TikTok with lightning speed:
- 58,000+ TikTok videos used the audio
- It topped Spotify's Viral Song Charts globally
- It was one of the first AI-generated songs to chart on Billboard
- Teachers reported students singing it ironically in schools
Why It Went Viral
The virality was driven by a mix of sincere and ironic uses:
- Sincere tributes — Some users genuinely shared the song as a memorial
- Ironic memes — Many users used the AI-generated audio over dramatic montages, satirizing the uncanny "AI accent" of the track
- "Kirkified" images — Charlie Kirk's face was edited onto other pop culture figures, spawning the "Kirkified" editing trend
- Crossover edits — Creators combined "We Are Charlie Kirk" with other trending sounds (including FAHHHH) for maximum chaos
How FAHHHH and "We Are Charlie Kirk" Crossed Paths
Both memes peaked during the exact same week in September 2025. Here's how they intersected:

| Sep 16, 2025 | Peak FAHHHH brainrot era | "We Are Charlie Kirk" song released |
| Sep 20-30, 2025 | Both sounds dominate For You Pages | Crossover edits emerge |
Crossover Content
Because both sounds were omnipresent on TikTok at the same time, creators inevitably combined them:
- FAHHHH + Kirk edits — The FAHHHH sound used as an impact marker in "Kirkified" meme videos
- Sound mashups — Remixes layering the "We Are Charlie Kirk" chorus with FAHHHH punchlines
- Dual reaction videos — Creators reacting to both trends in the same video, comparing the two biggest memes of the month
- "September 2025 Starter Pack" memes — Lists that included both FAHHHH and "We Are Charlie Kirk" as defining elements
Two Sides of the Same Coin
Despite their different origins, FAHHHH and "We Are Charlie Kirk" share surprising similarities:
| Feature | FAHHHH | We Are Charlie Kirk |
|---|---|---|
| Virality driver | Sound clip → TikTok audio | AI song → TikTok audio |
| Primary engagement | Audio-first content | Audio-first content |
| Ironic usage | High (brainrot edits) | High (ironic tributes) |
| Community creation | Remixes, vocal challenges | Kirkified images, parodies |
| Platform | TikTok-first, spread everywhere | TikTok-first, charted on Spotify |
| Cultural commentary | Post-verbal internet expression | AI's role in media and mourning |
The Key Difference
- FAHHHH is pure meme energy — it has no meaning beyond vibes
- "We Are Charlie Kirk" carries political and cultural weight — even when used ironically, it references a real event
This contrast is part of why they coexisted so well — FAHHHH provided the escape, while "We Are Charlie Kirk" provided the commentary.
The September 2025 TikTok Meta
For historians of internet culture, September 2025 was a landmark moment. The simultaneous viral explosion of FAHHHH, "We Are Charlie Kirk," and a host of other memes created a unique cultural landscape:

What This Era Means for Meme Culture
September 2025 demonstrated several important shifts:
1. Audio is King
Both trends were sound-first. In a visual-dominant internet, the biggest memes of the month were both sounds. This confirms TikTok's evolution into an audio-first platform.
2. AI Enters the Chat
"We Are Charlie Kirk" was one of the first AI-generated works to go genuinely viral and chart on Billboard. It showed that AI-created content can participate in (and drive) cultural moments.
3. Speed of Virality
Both trends went from zero to billions of views in under two weeks. The velocity of meme adoption continues to accelerate.
4. Irony is the Default Layer
Both trends were used ironically at least as much as sincerely. This reflects the default mode of internet communication in 2025: everything exists in multiple layers of meaning simultaneously.
