ByunTaeng is back~~~~~ ^_^~~~~~~,
The above interesting picture was taken during the KBS Gayo Daejun yesterday (30th Dec).
Taeyeon was like greeting to Nicole (KARA) after she has finished her performance, then Taeyeon suddenly putting her hand on her butt, and this precious moment was captured by a Fan.
This picture has become hot topic amongst netizens, and they've made comments like

• 'dear leader byuntaeng on the roll~!'/ ' hahaha byungtaeng strike...nicole is innocent... she can't get enough from the snsd members and now she recruiting new members...love it' '/ LOL, it looks like Taeyeon is saying "DAMN!! THAT'S A FIRM BUTT!" XD This is just pure win. XD'

If anyone of you cannot remember how Taeyeon got herself new nickname 'ByunTae', here is the link to refresh you.
Indeed ByunTaeng ~~~~~~~~~^___^~~~~~~~~~ Love it~~~~~
