The 'ㄷㄷㄷㅈ' meme began to gain traction in March 2020 with the release of rapper Mushvenom's advertisement video, "TFT Mobile Dudung Deungjang," which promoted Riot Games' auto-battler game, Teamfight Tactics (TFT) mobile version. It truly took off in April 2020, becoming a major topic whenever the ad played during League of Legends Champions Korea (LCK) broadcasts, with chat rooms being flooded with 'ㄷㄷㄷㅈ'. Its popularity extended beyond Korea, spreading to international viewers under the name 'DUDUDUNGA', and continued to be mentioned consistently until 2021.

The initialism 'ㄷㄷㄷㅈ' (ddddj) is pronounced by sounding out each consonant in Korean. However, the meme is widely recognized by its full phrase, '두둥 등장' (Dudung Deungjang), which was popularized internationally as "DUDUDUNGA." For English speakers, the most natural pronunciation to associate with the meme is "Doo-doo-DUN-gah."

'ㄷㄷㄷㅈ' is an initialism for '두둥 등장' (Dudung Deungjang). It is used to express something appearing suddenly, an unexpected situation unfolding, or the impressive arrival of a particular person or event. This meme originated from the catchy lyrics "Dudung Deungjang" in rapper Mushvenom's TFT mobile advertisement video. '두둥' (Dudung) is an onomatopoeic sound effect used in comics and other media when something appears, while '등장' (Deungjang) emphasizes the meaning of "appearance" or "to appear."

It was primarily used by gamers who enjoy League of Legends and Teamfight Tactics (TFT), particularly male and female viewers of esports like LCK, aged late teens to 30s.

• "A new champion, ㄷㄷㄷㅈ!"
• "When the ㄷㄷㄷㅈ ad appeared during LCK broadcasts, the chat was flooded with ㄷㄷㄷㅈ."
• "When HLE's Dudu was called up to the main roster, fans cheered 'Dudu ㄷㄷㄷㅈ!'"
• "Finally, the long-awaited new game ㄷㄷㄷㅈ!"

Since this meme originated from a specific game advertisement, its meaning might not be properly conveyed or may seem out of place to those unfamiliar with the game or esports culture. Additionally, as the meme's period of popularity has passed, its usage frequency may have decreased, so it's important to use it appropriately.
