On November 19, 2017, Trippie Redd teased this song on Instagram Live, saying: “Can you guess who’s featured on this? He loves cactuses”, before singing the hook of Travis Scott’s “90210.” The following day, Travis tweeted the lyrics of this song’s hook, essentially confirming that he was featured on the track. Over the following days, Trippie continuously teased the song on Instagram, saying that he was waiting for Travis to send back his verse.

On November 29, Trippie uploaded another video to Instagram, teasing Travis' part to the song. Trippie originally hinted on the post that he would release the song after the post receives 100,000 comments saying “1400/800”, however, it was deleted later that night. Not long before it was deleted, Travis Tweeted about leaks with several angry emojis, leading some to believe that was the reason why Trippie deleted the video.

The song was released on December 5, 2017, and marks the first collaboration between the two artists.

The title seems to be a reference to the groundbreaking 2008 Christoper Nolan Batman film, “The Dark Knight.” It also seems to make reference to 6ix9ine’s “Gummo,” which is where the ‘Dummo’ from the title comes from. They were recently engaged in beef after they had a fight backstage at ‘Day ‘N Night’ festival.

It’s also worth noting that the melody that Trippie uses in the hook is very reminiscent of the melody he used on XXXTENTACION’s “Fuck Love.”
