"Head, shoulder, knee, arm"

Translation: 머리, 어깨, 무릎, 팔

[Ajla_G]

"Swaaag check"

[Peter71641]

Mamamoo 'HIP' check and you remember it easily.

[Andy513708]

That's not how this song goes !

[jaisaige]

REMIX!!

[Yquerea]

Hip hey! Hip, hip, 머리, 어깨, 무릎, Hip!

Haha it's Mamamoo's Hip reff~

[Andy513708]

It didn't click at the time, but while Hip was my first thought too, it's actually closer to Sleep in the Car, where Byul references the proper Korean version of the song, "머리, 어깨, 무릎, 발" (head, shoulder, knees, feet)... except here Duo has replaced 발 (feet) with 팔 (arm). Because that's how Duo rolls...

[Sebihoo]

Hip!

[hwanghaedo]

That was my answer which was marked incorrect. What happened?

[GraceKim344744]

Should be head, shoulder, knee, foot

[GraceKim344744]

Should be head, shoulder, knee, foot

[VIXX_LuvMyself]

Oops! It seems like Duo messed up the lyrics:

Head, shoulder knees and toes...

[Andy513708]

Not exactly; the Korean version of the song (at the least the version I've encountered https://www.youtube.com/watch?v=YMUBFumKXHA), is actually "head, shoulders, knees and feet" (머리, 어깨, 무릎, 발)... rather than 팔, as here, meaning "arm". That may also be a valid version, though.
