Taengoo was just having some fun with a toy which makes the sound “Oops” when a pen goes into the …. and there you go, a new nickname for her – Byuntae Yeon. Byuntae means pervert in korean. Come on, give the girl a break. She’s turning 21 in less than 3 months time. She’s an adult now and I personally won’t call her that because I feel it’s not appropriate. If playing with the “Oops” toy gives her the nickname byuntae, then i guess most of us should be given the byuntae nickname with perhaps the word “super” in front.
