I have noticed throught the years that SNSD say "i am Girl's Generation" a lot of times when people praise them or say something positive about them just to give a few examples
When Sooyoung was learning a dance very quick the coreographer tells her wow you are learning it so quick and Sooyoung smiles and replies "I am Girl's Generation"
Same thing with Yoona in Power Up dance challenge i think Seulgi praises her for learning the dance fast and Yoona just says "I am Girl's Generation" while smiling and pointing her fingers to herself
There are other times when they use that phrase and i have seen even other idols using the phrase like "they are Girl Generation" when praising something like popularity about them so it's a phrase that even other idols (2nd generation) Acknowledge and use which i found kind of interesting, are there any other group's that use their group's name like that?
