MASC is a 4-member male idol group under the agency JJ Holic Media, formerly famous for their artists Yurisangja, N.CIA, and "Kpop Star 3" Top 10 entrant Nam Youngju. The group consists of members Woosoo, 26, ACE, and Heejae. The group debuted with their 1st mini album, Strange, on August 18, 2016.
Group Name and Meaning
The group name "MASC" 마스크 is an abbreviation for “Masculine.” It's a fitting name since everyone in the group debuted at an older than average age, with three members over 25 and the maknae at 21. They are a group of grown men with a mature, masculine appeal. This could help set them apart from some of younger groups who debuted in 2016.
Official Greeting (Insa 인사)
"Masc, maSc, masC!" - The word MASC in Korean is three syllables: Ma 마, Su 스, Ku 크. Unlike English where words are pronounced with an intended emphasis on a certain syllable, like how the word "continue" is said like "conTINue," in Korean all words can be be spoken accenting any syllable without changing the meaning or mispronouncing the word. So the team is using the accent game to repeat their group name in a fun, memorable way.
