Over a "sinister" beat, the song begins with Offset rapping in the chorus and first verse about his diamond jewelry and having shooters by his side, while switching his flow and using his signature triplet rhyme scheme.
[1] In the second verse, 21 Savage immediately compares himself to North Korean leader Kim Jong-un as a joke, while rapping about how he is still hanging out with the "killers" and "gorillas" with guns.
[1][2] The third verse finds Travis Scott in Auto-Tune laced vocals, referencing his drug use and being a "Nike" boy.
[1] Gary Suarez of Consequence Of Sound wrote, "While less overtly villainous than his deadpan cohort, Offset lets Savage’s sinister sensibilities rub off on him at times, particularly on opener 'Ghostface Killers'.
"[4] Trent Clark of HipHopDX also considered "Ghostface Killers" the best track from Without Warning, adding that "The Travis Scott inclusion is an obvious draw but when you have a bridge, a chorus and layered instrumentation, it's not a coincidence the song quality can raise above mixtape level.
