He’s on fire, peek of his career so far, he’s also fly, has cool fashionable clothes and such, put it together and he’s a FireFly
Firefly was also a show on Fox about a crew on one of many spaceships that left Earth after it was no longer able to sustain all of the people who inhabited it. This could be a reference to the fact that CG escaped his life as a nobody in the South and in the Projects for the life he has now.
Regarding the previous line, “we got so high,” you can’t get much higher than out of this world which is where Firefly takes place.
There’s also a shout out to Firefly in Glover’s other project, Community, where Abed [Danny Pudi] and Troy [Donald Glover] make a pact that if one of them dies, the other stage it to look like a suicide in protest of the cancellation of Firefly.
