It's a nonsense word. On their variety show, Run
BTS, the
BTS members were playing a game like telephone, where you have to read your teammates lips while wearing headphones that are blasting
music. J-Hope was trying to mouth the word "carbonara" to Jimin, who read the now infamous word, LACHIMOLALA, to the final player, Jin. Despite getting the wrong "message" Jin saved the
day with his genius ways and got the right, answer, "carbonara," to everyone's surprise.
