Young Thug announced the release date of Slime Season 3 through a funeral procession at SXSW in Austin, Texas.

Lyor Cohen teased the funeral on Snapchat, saying, "Today in Austin, we're gonna bury Slime Season 3".

said, "Every song justifies its spot: the Allen Ritter-produced "Drippin'" serves as a standout, exhibiting a staccato delivery and manic yelling, both of which are new to his already vast sonic vocabulary".

[8] Narsimha Chintaluri of HipHopDX said, "Young Thug's extensive catalog is spotted with dynamic moments and this project seems to forgo such progressiveness.

[14] Brooklyn Russell of Tiny Mix Tapes said, "Slime Season 3 is as celebratory, emotionally rich, and life-affirming as a good funeral should be but never is.

[17] Brian Tabb of Pretty Much Amazing said, "Slime Season 3, while still with its flaws, is the perfect introduction to those wondering just where the hell popular hip-hop has come, gone, and will soon go in the snowballing south".

[10] Scott Glaysher of XXL said, "Overall, Slime Season 3 stacks up well against Thug's colorful catalog and is undoubtedly the most listenable mixtape in the series thus far".
