  • Dancing Queen – Self-explanatory.
  • 피오나 공주 (Fiona Gongju) – Princess Fiona – Sooyoung teasingly gave Hyoyeon this nickname after she had gained ~10kg during her time spent in China learning Mandarin. Unaware as to the true intention of the moniker, Hyoyeon happily accepted it because the title contained the word “princess”.
  • 효랭이 (Hyoraengi) – Tiger Hyo – Tiffany’s mispronunciation of 호랑이 (horangi), Korean for “tiger”.
  • 효땡(이) (Hyoddaeng(i)) – aegyo-ified version of “Hyoraengi” (most often used by Sunny)
  • 김열살 (Kim Yeolsal) – ten-year-old,
  • 김초딩(Kim Choding) – “elementary schooler”, and
  • 효 어린이 (Hyo Eolini) – “Childish Hyo” are all nicknames for Hyoyeon’s childish mannerisms.
  • 효바람 (Hyobaram) – “Casanova Hyo” (바람 baram means “wind” in Korean, (jokingly) implying Hyoyeon flits from man to man) – Sooyoung’s nickname for Hyoyeon when she was a fellow trainee in SM. As a young female trainee, she was admired and looked after by most if not all of the male trainees.
  • 효숙이 (Hyosooki) – A pet name given to Hyoyeon by the male trainees at SM. Sooyoung said she actually thought it was Hyoyeon’s actual name when she first joined SM. (Sooyoung also has Hyoyeon’s cellphone number saved under this nickname.)
  • 효레나룻 (Hyoretnarut) – “sideburns Hyo” (구레나룻 = sideburns) – Nickname given by fans for when Hyoyeon had cut her sideburns because they were too long. (See video)
  • 요년(아) (Yonyeon(ah)) – A slightly distasteful way to call a girl; technically the equivalent to calling someone a “bitch” in English–either playfully or offensively. (Unintentionally) Given to her by French fans who, according to Sooyoung, couldn’t pronounce the “H” sound in Hyoyeon’s name. So when they heard her name being called when they had arrived at Charles de Gaulle Airport for SM Town Paris in 2011, they heard “Yonyeon!” instead of “Hyoyeon!”

  1. Hi, I’m new here and I’m indonesian. I’m so happy to have found this fansite. This is my first comment.
    first of all, I’m grateful that there’s Hyoyeonnies out there will always support her 🙂
    I’m totally A huge fan of Hyoyeon since I got snsd fever last year. Not that I didn’t know anything about snsd, I’ve known snsd since kpop rules the world. but I wasn’t into kpop at that time.
    The reason I love snsd its their great performance on stage. I think they are the greatest girlgroup in the world. They are adorable, funny, charming girls. One person that caught my eyes for the first time was hyoyeon. She is really funny. she is honest. I can say it for sure that she is an adorable girl. she has great personality. There’s not enough words to describe it. She has many differents charming points. That was my first impression of her. Then I found out later that she is the queen of popping or the dancing queen, and I said wooah this girl is amazing. She’s talented. Only people don’t see it that way.
    If some fans/sones like girls generation based on their looks “pretty goddesses”, as for me I like Hyoyeon because of her personality. She makes us laugh. she never fail to make people laugh and she is a beautiful girl. ONe person could make others happy is the greatest thing.
    I wish she gets more chance to shines in the future, not only dance related but also other things such as acting, cf, photoshoot. I thing Hyoyeonies are dying to see it too 🙂

    • Awww ; ; Thank you SO much for this comment!! Personally I’m the same way; I love her personality and find her so very charming and beautiful as well 🙂 We Hyohunnies really are dying to see more sides to Hyoyeon!! ♥

      Hyo ♥
