While JT was incarcerated, Yung Miami continued promote the group's music, saying: "When she was in jail, I was going to strip clubs and I would pay a DJ $20 to play the song. It started taking off. " Later that year, the track was included in Quality Control's compilation album, Control the Streets Volume 1, and it went to number five on the Billboard 200. It also topped Billboard's R&B/Hip-hop chart. The official music video for "Fuck Dat Nigga" came out in January 2018 and featured an appearance from rapper Trina.
