The Girl Group
- Base Breaker: The whole Sulli incident, since she abruptly ended F(x)'s Red Light promotions by being absent on music shows until SM Entertainment could not hide it anymore. She officially left the group one year after the whole controversy began to continue acting. It's not helped by the fact she had shown signs of leaving a year before the whole thing even started.
- Krystal's absence in SMTOWN since her sister was fired from Girls' Generation has not gone without notice by fans. She also received many death threats from SHINee fans for the sexy photoshoot she had with them.
- Luna's BoA face.
- Amber's tomboyish attitude still doesn't fly well in Korea, but international fans are more understanding.
- The fact Victoria is perfectly set for leaving the group when their contract ends, having her own studio in China from where she can continue her career with no problems after f(x) ends, has started to worry fans that f(x) will truly end faster than they thought.
- Crowning Music of Awesome - This video of Luna singing "Bring Me To Life" with TRAX. Considering that her voice is more refined now, if she sang this again, it would be even more amazing.
- Their album "Pink Tape" is considered one of the best K-pop albums ever, certainly the best of the year it was released, and the trend continued with "Red Light" as well.
- Ear Worm: Quite a few.
- "Electric shock (EH EH) electric shock."
- "Rum pum pum pum."
- What Do You Mean, It Wasn't Made on Drugs? - Their "art film" for Pink Tape which can either be a very artsy video... or Nightmare Fuel (especially the beginning part).
