Why Koreans care

학예발표회 (hagye balpyohoe) is a school showcase where each class performs songs, dances, or plays for their families. That framing explains why the conversation below the stage imitates parents discussing costumes, children, and the performance.

In the Korean comments

At 4:39, one comment reads, in translation, “So that’s what the clothes were—they matched the outfits from the members’ childhood photos.” Another similarly says everyone arrived dressed exactly like their old pictures, offering a specific costume detail to check on a second watch.

What the words mean

학부모깔 (hakbumo-kkal, school-parent look) does not simply mean that someone is a parent. 깔 (kkal, look or vibe) is casual slang here for the styling and air of a character; commenters use the phrase jokingly because the members so convincingly resemble well-dressed mothers attending a school event.
