Stands for "Roll Like A Buffalo" This phrase was used in one of the K-pop group "Exo"'s teasers as part of the song "Two Moons" by Exo. This phrase is spoken by the leader of one of Exo's subgroups, Kris, of Exo-M and is used frequently by many Exo fans. They think it might be a reference to his hometown of Canada. Fans use it in replace of "LMAO", as a sign of great humor.
