But everybody thought it was jokes though
They half right, the joke is
I got flow so don't act like
You ain't sittin' there with your friends like, it can't be
I know Donald Glover, he weak man, he campy

from Childish Gambino – Fire Fly Lyrics on Rap Genius

Meaning

When I first heard Donald Glover was rapping as “Childish Gambino,” I immediately thought it would be some Lonely Island kind of thing where he rapped a lot of jokes and stupid shit. I was wrong, and so is anyone who still thinks that. He has such an advantage as a rapper being a writer and comedian because he can write such sick burns and really intellectual and witty rhymes. His word play is ridiculous, like using the word “campy” meaning effeminate. So the real joke is… that he goes harder than most rappers that are signed and he is making a career out of it because he’s good at it, not because he doesn’t have other career options. He’s taking rap to a new level
