The experience of being high, especially on LSD. Derived from the 1967 song "Flying High" by Country Joe & The Fish.
Man, the other night, Steve and I were totally flying high! We each took a tab of Orange Sunshine, and I felt like I was merging with all the furniture in the room!

"And I went flying high . . . all the way." -Country Joe & The Fish

To have an attitude of complete confidence. The word envisions a person above the rest of the people, symbolizing how they don't care what other people think since they're confident being themselves.
The word is used a lot in hip hop lyrics to convey this meaning.

A tongue-in-cheek form of condolence used in the K-pop community on Twitter, similar to "RIP" or "F."

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.
A: Fuck, my favorite group is competing against BTS at a music show next week.
