The song is the 36-year-old singer's second single since "Gangnam Style" debuted in April 2013, and features Snoop Dogg. The music video also includes cameos by G-Dragon from Big Bang and CL from 2NE1.
The video begins with a hungover Psy and Snoop Dogg, and goes on to recount their exploits from the night before. The pair drink massive amounts of soju, visit noraebang and an amusement park, and start a brawl after Psy carelessly tosses a spoon onto another table.
"What I thought was I should refresh myself, and people, that I'm doing something different," Psy told MTV before the song's release. "After that hook part was done, right away I thought about Snoop Dogg. He's hanging over every day, so, wow, I should call him!"
"We [shot] that music video in Korea," he continues. "Snoop and I both had only 18 hours. ... Snoop's calculation was 8 hours of shooting and 10 hours of partying. That's what he thought, and honestly, that's how I convinced him to bring him to Korea."
