Stokeley Clevon Goulbourne was born on April 18, 1996, in Fort Lauderdale, Florida. He is of Jamaican descent. He grew up listening to Busta Rhymes, Missy Elliott, Wu-Tang Clan, and Lil Wayne, among other artists. He has said that his parents often played Jamaican music around the house. Goulbourne's father—a rapper who used the stage name "Sin City"—would often force his son to focus on writing his own rap music. In 2013, Goulbourne was sent to a juvenile detention center for possession of "around $10 worth of weed", where he met XXXTentacion. The duo became friends and frequently collaborated on songs after being released from detention.
Following Goulbourne's release from detention, he formed the rap group "Very Rare" with XXXTentacion and released his first song "Catch Me" on the streaming service SoundCloud. Goulbourne eventually co-founded XXXTentacion's collective Members Only after the release of Members Only Vol. 1, a collaboration mixtape with XXXTentacion, in 2015. The mixtape would eventually be followed up with Members Only, Vol. 2 and then Members Only, Vol. 3 on June 26, 2017.
Goulbourne released multiple singles on the SoundCloud platform including "Catch Me Outside", "Where's the Blow" featuring Lil Pump, "Stunt!" featuring UnoTheActivist, "Life Is Short", "Like a Soccer Mom", "Take a Step Back", and "BabyWipe". Goulbourne has performed twice at the Rolling Loud Festival and has released songs with other artists including Offset, Lil Yachty, A$AP Ferg, Lil Peep, Desiigner, and Denzel Curry. Goulbourne has also collaborated with artists from the 88Rising label including the Higher Brothers and Keith Ape. Goulbourne also worked with Timbaland, who he had previously said was his favorite producer.
In May 2016, Goulbourne released his first mixtape Drown in Designer, which included the songs "Take a Step Back", which was later certified Gold, and "Where's the Blow". In June 2017, Goulbourne released his debut commercial mixtape You Will Regret under Victor Victor Worldwide and Republic Records.

Goulbourne was close friends with XXXTentacion before they both started rapping. They met in a juvenile center in 2013. Goulbourne said in an interview with Adam22 that he was surprised by X's criminal charges. Whilst in jail, X had taught Goulbourne about different rapping cadences. After the duo were released, they met up with the intention of committing home invasions but instead began releasing music together. The rappers founded the collective Members Only. In 2017, Goulbourne and XXXTentacion embarked on The Revenge Tour with Craig Xen. The tour was postponed following the shooting of XXXTentacion's cousin. By late 2017, the two had parted ways and begun working on their own projects.
