"What are Moonlight Gymnastics?" Psy asked his 3.5 million Twitter followers on Monday.

The K-pop phenomenon went on to explain that it was the concept for the series of shows at Seoul's Olympic Gymnastics Arena, on Dec. 22, 23 and 24, that will be his dramatic return to the stage after an eight-month hiatus.

In a tweet that went well beyond 140 characters, the King of YouTube explained his mischievous concept for the holiday performances.

"What is Moonlight Gymnastics? It is a scolding when you do something that's against your 'class.' As a member of society, how much effort did you put into this year to keep that 'class?'" Psy asked.

"I too had a hard time this year. It's already been a year since I ended up getting pushed into promoting abroad without even realizing it. The man with no 'class' in particular tried to have the 'class' of a small yet spicy pepper. After jetting forward with the 'class' that I do not have, all that's increased are my English and stress."

The record-breaking rapper also vented his frustrations of spending a year just promoting "Gangnam Style" and "Gentleman."

"Before I used to go to festivals and do 15 songs, but now I've lived an entire year with just two songs," Psy wrote.

"For all of us who tried their best this year, let's do something that fits our 'class' for just one day! Let's do some Moonlight Gymnastics on the moonlit night of Christmas at the Gymnastics Arena that's known to be the best place to do gymnastics."

But although Psy might be burned out on performing "Gangnam Style" and "Gentleman," in a cover interview in this month's issue of L'Uomo Vogue, he admitted the latter song has allowed him to breathe a sign of relief.

"After 'Gentleman' was out, I was really satisfied with what it had done, because it proved that I was not a one hit wonder, a lucky shot," Psy said.

"Nobody can ever label me that now. 'Gentleman' has 500 million views right now, the song also hit number one in 81 countries, and I am really relieved by that. Now I can really do what I have to do, comfortably. I don't have to make another dancing phenomenon, I am just going back to where I came from and it's really comfortable right now."

"Gentleman" has broken YouTube records in five categories, including most views in a video clip's first 24 hours, the most views in any 24-hour period and the video to reach 200 million, 300 million and 400 million views the fastest.

"Gangnam Style" remains the most watched video clip in Internet history, with over 1.8 billion views.
