The adjective 'y' is probably not the first thing that comes to mind when thinking about Girls' Generation's Seohyun.

Descriptions such as 'pure' and 'girl next door' seem more fitting for a wholesome girl like Seohyun, right? Wrong. On the August 26 airing of 'Weekly Idol,' Hyoyeon advocated the maknae as the iest member within the group. 
 

When MC Jung Hyung Don asked the girls who the 'iest member' was, Tiffany picked Yuri. However, Hyoyeon disagreed, picking Seohyun as Girls' Generation's iest member. She explained, "She is unexpectedly glamorous," bringing attention to Seohyun's mature, womanly side. 

The maknae thanked Hyoyeon for the generous compliment, but was flustered when the MCs requested her to take part in a y dance battle. You can check out the y dance battle below!
