Sorry to annoy you with PSY's Gangnam Style again, BUT I love reactions too much. Just seeing people grin, dance, and laugh.
"What's going on dude?!" and "What on Earth?!" fits the music video so well.
Um, how do you say "Hyuna"? "Hyou-nah"? According you YT comments, the people in the vid are saying her name wrong.
