 On October 23 , 2012 , after receiving much critical acclaim from the hip hop community , outspoken rapper Shyne took to Twitter to run down on the album , calling it " trash " and the production horrible . West Coast rappers Nipsey Hussle , Schoolboy Q and Game quickly took offense to this , with Game calling Kendrick non @-@ confrontational in that he wouldn 't respond to Shyne . Kendrick responded to Shyne 's comments on October 26 , saying that he is not a sensitive person and was unfazed by his comments . In addition he said Good Kid , M.A.A.D City was not necessarily a " classic " as some have called it , but " classic worthy " if enough time passed . Kendrick also referred to Shyne in his song " The Jig Is Up " saying , " I pray to God this beat good enough for Shyne " . After this Shyne stood by his comments and called Game his " little son " . Game responded with a freestyle calling out Shyne , titled " Cough Up a Lung " . Shyne then responded with his own diss track , towards Game named " Psalms 68 ( Guns & Moses ) " .
