Black Friday is the second mixtape by American rapper Lil' Kim, released on February 14, 2011. The title track is a response to Nicki Minaj's song "Roman's Revenge". The mixtape also contains the track "Grindin’ Makin’ Money," a collaboration which features rappers Birdman and Nicki Minaj, which Kim claims ignited the feud between her and Minaj, as well as another diss song towards Minaj titled "Pissin' on 'em".
Black Friday was panned by music critics. Kid Fury of Vibe described its content as "tragic shit" and commented that the mixtape "lacks consistency, edge, and originality".Slant Magazine's Huw Jones gave it one-and-a-half out of five stars and felt that its production lacks "originality". Jones also panned Lil Kim's lyrics and disses towards Minaj as "inane", writing that "there are some pert jabs dotted among the tactless insults, but for the most part, it's a senseless rant". Kazeem Famuyide of The Source wrote that "I know it's a dated name ... but I don't think it’s that crazy as far as appealing to her hardcore fan base". Jozen Cummings of XXL wrote facetiously, "It's not that we refuse to pay for music, we'd just much rather have an option to not do it. If you force any price tag on us without giving us a decent amount of free music to sample from, we're scoffing at that $9.99".
