In an episode of BTS run, BTS Jimin was playing a game where you guess the word the other player says by his mouthing. In one round, J-hope said "carbonara" and at first, Jimin said, " Tony Montana" but later changed his answer to "lachimolala". Somehow, Jin still managed to win by repeating "carbonara", but the Jimin's moment was imprinted in Armys heart. Forever, borahae. (Note: Used only in Army inside jokes, not to be used formally.)
"Could you add some of the tomato sauce you cooked to my delectable lachimolala?"
It is not a real word, but it is what the famous K-pop boyband member Jimin, heard instead of Carbonara in an episode of Run BTS. It has remained a fan favourite since then
"Who's your bias?" "lachimolala"
