Perfect all-kill (Korean: 퍼펙트 올킬; abbreviated as PAK) is a music chart achievement in South Korea where a song simultaneously reaches number one on the real-time, daily, and weekly components of iChart, a music chart ranking aggregator operated by the South Korean web entertainment publisher Instiz Corporation, the operator of the Instiz web forum.[1][2]
The term "perfect all-kill" was first used when the song "Nagging" by IU featuring Seulong ranked at number 1 on all Korean music charts in June 2010.[3] Although Instiz iChart was launched in March 2010, it does not list 2010 records. The artist that holds the record for the most number of songs to achieve a PAK is IU with 22 songs. The song with the most hourly PAKs is "Ditto" by NewJeans with 655 PAKs.[4] "Celebrity" by IU holds the record for a solo act with 462 PAKs.[5]
