Not every trend explodes. The ones that do usually share the same signals:
1) Cross-platform lift. You see the same topic on TikTok, X, Instagram Reels and Reddit within 24–48 hours.
2) Simple remixing. It’s easy for anyone to copy the format and add their twist.
3) A clear “why now.” News hook, product drop, celeb moment, or a technology shift.
4) Short payoff. Viewers “get it” in under 5 seconds.
5) Emotional spark. Awe, anger, cute, or useful—neutral doesn’t spread.
Takeaway: If you spot three of the five, draft your post/video immediately and ship within the hour
