Sunmi sang the part as "Gee Gee Gee Gee aka aka aka" [ "aka" means baby in Korean]
and that cracked me up far more than just the normal lyrics.

I was (and I am) not a fan of Wonder Girls but I feel warmer and warmer towards them because of our girls. ^^
I hope Wonderfuls would feel the same way.
Wonder Generation all the way.
Thanks a lot for sharing and translating, jstn.
May I say that I miss your translations? >.<
