The phrase “I purple you” was originated by V during BTS’ 3rd Muster in November 2016. On March 29, BTS appeared on the KBS 2TV talk show special Let’s BTS .

Purple is the last color of the rainbow colors, so it means I will trust and love you for a long time," he said. Both BTS and ARMY were impressed he knew this, but then V revealed he was just kidding.
