목 꺾일라 translates literally to "you might break your neck." It's a colloquial Korean phrase used as a taunt or strong warning.
In the song, BLACKPINK uses it mockingly in the line "고개들이 돌아 진정해 목 꺾일라" (Heads are turning, calm down, you might break your neck). It's not about actual violence but a badass, swaggering way of saying "we're so stunning that everyone stares, so don't hurt yourself." This snappy, attitude-filled phrase is rare to find in everyday vocabulary and perfectly captures the group's uniquely confident energy, making it an unforgettable and educational expression.
BLACKPINK is back and they want everyone to know they're still on top. The song kicks off with the line, "컴백이 아냐 떠난 적 없으니까" (It's not a comeback, 'cause we never left), making it clear they believe they never lost their spot. They're so confident in their success that they tell everyone else to just give up when they arrive: "When we pull up, you know, it's a shutdown / 간판 내리고 문 잠가" (When we pull up, you know, it's a shutdown / Take down the sign and lock the door). It's a bold way of saying the competition is over.
The whole song is full of these kinds of flexes. They brag about their wealth with lines about Lamborghinis and VVS diamonds, and even say they don't buy luxury items, they "request it". They directly address anyone who doubts them, saying "Praying for my downfall, many have tried, baby". The lyrics are all about their power, fame, and shutting down anyone who gets in their way. It's a super confident track that announces their continued dominance in the music world.
