I guess it all goes somewhere, you know that
Like that bullshit you talked before Culdesac

from Childish Gambino (Ft. Beldina Malaika) – Not Going Back Lyrics on Rap Genius

Meaning

Possible reference to the last song on I AM JUST A RAPPER 2 entitled “Nowhere to Go,” which was the last release before his third album: Culdesac.

He is comparing what he did with the song about Rashida Jones, which was throw that shit away, with what people did with the shit they were saying before he dropped Culdesac and shut the haters up
