the iconic intro

In the Korean comments

Commenters call the Jiwoo–Jueun pairing 우주즈 (Ujujeu, the “Uju” pair), which enables a playful space pun because 우주 (uju) means “universe.” One comment reads, in translation, “Ujujeu’s shoulder shake has enough impact to shake the universe.”

What the words mean

무대 찢었음 (mudae jjijeosseum) literally says someone “tore up the stage.” Here it is casual, emphatic praise meaning that Ujujeu delivered an outstanding performance.
