I did learn ballroom dancing and tap. I did think it's a dance of sort. It's not any sort of dance I'm aware of but then again, I'm not a professional dancer.
The reason why I said this is a girl with down syndrome making a chuuni pose was to inform of the ridiculousness of the pose. The reason why I said she looked like she had a down syndrome was because this particular cover with its facial expression and its pose reminded me of a classmate who had a down syndrome back in school.
Anyway, since you called me back here, please answer the question.
