What is a 완판녀? I did some searching today and I’m still not completely sure but I get the impression that it is a women that is capable of selling things. And not just like normal sales but making the things they advertise sell out. People want want wanpannyeo’s are selling.
Why did I look this up? Because of this:
"소녀시대 잡지 품절, `완판녀` 등극…1등은 서현 2등은 윤아"
This means something like “Girls Generation’s Magazines Sell Out, `완판녀` crowned 1st place is Seohyun 2nd place is Yoona.”
The nine girls were on the cover for Marie Claire recently. It was a special edition of Marie Claire that had a cover for each of the nine members. So this is basically saying Seohyun’s version sold out first and then came Yoona.
잡지 - magazine
품절 - to be sold out / to run out of stock
등극 - crowned / to be crowned
등 - rank / ranking
