Today, I won't forget the energy and cheers of STAY at Palco Mundo! 🎸⚡

What happened

Stray Kids thanked STAY for the energy and cheers that filled the Palco Mundo stage, in a post tagged for Rock in Rio 2026.

Why Koreans care

“STAY” is not merely a request to remain: it is Stray Kids’ fandom name. The official hashtag “You Make Stray Kids Stay” turns that name into a wordplay suggesting that fans are what keep Stray Kids going.

In the Korean comments

The 12 Korean-language comments supplied here are warm, but one identifies the crowd’s group singing as the affecting detail. It reads, in translation, “Stray Kids’ stage is great, but seeing them perform surrounded by STAY singing together feels somehow moving, impressive, and wonderful.”

What the words mean

“꽉 채워준” (kkwak chaewojun, filled completely) literally describes filling something until it is packed. Here it is an affectionate, emphatic way of saying that STAY’s energy and cheers saturated the Palco Mundo stage, not simply that the venue contained a full audience.
