Noh Hong-chul

He had a cameo in the popular music video "Gangnam Style" which featured his trademark pelvic thrusting jeojil dance (저질댄스).

Noh Hong-chul studied mechanical engineering at the Hongik University. After finishing his mandatory two-year military service, he created the online fashion malls Nohongchul.com and Dream and Adventurous Hongchul-Land Corporation which sell a range of party supplies. Noh Hong-chul also ran Hongchul Tour which provided budget trip services in China; he sometimes personally guided his customers during these trips.

Noh Hong-chul's television debut came on Mnet in early 2004 when he hosted the cable TV show Dr. No's Pleasure Street (닥터 노의 KIN길거리). After the success of the show, he joined the free-to-air MBC program Come to Play (놀러와) as a joint panelist. In April 2005, he became a founding member of variety show Infinite Challenge. He was featured in a commercial for the GM Daewoo Matiz. The ad showed caricatures and photos of him inserted into the hood (bonnet) and doors of his red Matiz car (nicknamed Hong car 홍카, a play on his name and the word hong which means red). Noh Hong-chul had a brief cameo in Psy's music video "Gangnam Style". He was shown thrusting his pelvis in his trademark lewd dance or jeojil dance (저질댄스) while standing above Psy rapping in an elevator. His seven-second appearance in the video became a worldwide "sensation within a sensation" and he was, separately from Psy, invited to appear on US television. He made an appearance in Psy's video "Gentleman" alongside the rest of the Infinite Challenge members; and in Sistar's music video, "Touch My Body" alongside Jung Jun-mo. On July 16, 2026, Noh shared plans on social media to create a hotel — or possibly a small capsule hotel or hostel — built around the concept of "predictable eccentricity." The announcement drew added attention as it came shortly after he had disclosed an uncomfortable experience during a trip to the United Kingdom, where he was refused a refund after the air conditioning at his hotel malfunctioned during a heatwave.

On November 8, 2014, Noh Hong-chul was arrested for drunk driving. He later issued an apology and withdrew from the television programs he was participating in, including Infinite Challenge and I Live Alone.
