Nan Molla

NAN MOLLA is a lyric phrase that the leader of BTS, RM sang out in the song for their album Love Yourself.

I don't know, nan molla comes from the lyrics of a song called Fake Love made by South-Korean KPOP idol group called BTS. The romanized lyrics of the song say "Why you sad? I don't know, nan molla." If you ask any ARMY or BTS fan why they are sad, they will probably say nan molla.

the only answer acceptable for “why you sad?” ; the line ARMYs have mysteriously made a meme

If you would ask any ARMY on the earth "why you sad?" then they would probably (100%) say : "I don't know nan molla"

It's because of the song "Fake love" from BTS.
Check it out on youtube !! :)

LOVE YOU ARMY !
