Kosuke Kitajima
During the 2004 Summer Olympics in Athens, Kitajima generated buzz for his primal screams of exuberance after edging out Hansen in the 100 m and 200 m breaststroke for the gold. At a pool side interview (3'24") following his victory in the 100 m, Kosuke Kitajima also popularised the phrase 'cho-kimochi-ii,' meaning "I feel really good." The word went on to win the 2004 U-Can Neologisms and Vogue Words contest.
