Slime Language was released on August 17, 2018, the day after Thug’s 27th birthday. The project is Thug’s first full-length offering since June 2017’s BEAUTIFUL THUGGER GIRLS. With Slime Language, Thug continues post- Hear No Evil with his 2018 theme of honoring his deaf brother, Greg. The project’s artwork features the phrase “Young Stoner Life” spelled out in drawings of American Sign Language, and of course, the title Slime Language itself is literally a play on “sign language.” In promotion of the project, Thug sent live snakes to several media outlets, including Genius, Complex, and XXL. The snakes came with the album’s guest list. Thug later updated this list on August 14, 2018, along with announcing the release date and revealing the cover art. The project boasts features from many YSL signees, including Gunna and Lil Keed. It also features Thug’s long-time girlfriend Jerrika Karlae and his sisters HiDoraah and Dolly. Other frequent collaborators of Thug’s also make appearances, such as Lil Uzi Vert, Lil Baby, and Jacquees. Wheezy, Turbo, Keyyz, and more contribute production to the project.
