*What he wrote is "Heung Buja", there's no exact translation to this, 'Heung' means being excited/hyped, 'buja' means 'rich'. It's a web slang for (usually) performers who are able to show their excitement on stage :D Yonghwa's often called 'heung Yonghwa' by fans and nonfans because of his energized stage manner ^^
