The term was taken from the Soulfly song "Flyhigh" where it gives me energy to flap my wings and fly.
I'm
flying high with my brother while
playing pool! Other times though, I flyhigh myself while
working on my computer with music playing. Going into the beyond, people are flying high in the party!
