Origin: "Fly high, X1" was the slogan of Korean idol group X1, whose members were chosen from the competition reality series "Produce 101." In January 2020, just five months after X1's extremely popular debut, a voting corruption scandal put into question the legitimacy of some of the chosen members and the group disbanded. "Fly high" was initially used by X1 fans in earnest to grieve for the loss of their group and was soon appropriated by non-X1 fans as a meme due to lack of sympathy for the circumstances leading to X1's disbandment. Fly high, X1.
