And I'm-a flirt with this new girl
And I'm-a call if it don't work

from Childish Gambino – Heartbeat Lyrics on Rap Genius

Meaning

He’s trying to move on and see other people, but he can’t find the right girl so he keeps going back to the ex.

Unlikely, but why not? This is also a very possible reference to Ludwig Göransson starting to work on the TV series New Girl. While Ludwig is the producer (with Donald) on most of the tracks of the album, he is not the producer of this one — he’s away flirting with a “New Girl” and will come back to working Childish if his own career doesn’t take of (he’ll come back anyways!).
