Seum Dwa means: Running Man, a Korean Urban Action Variety Show. Kim Jong Kook wanted his children, Haha, and Gary to create a memorable trend phrase in 2011, which was SEUM DWA. These two words come from the Korean word “seumni-da”, which means rightunderstood. It sounds almost like “seumdwa” when it is pronounced quickly.
