[28] "The PiS media would like to take care of Mata-senior / He's a holy man / And what I do – it's my choice / And I'll answer for it myself one day / But first I'll answer you, so listen carefully / Fuck Polish Television / Jacek Kurski – suck my dick / (Stop stalking my family, you whore) / Because I'd like to grow up in peace."

On 30 March 2021, he released the single "Patoreakcja", in which he expressed his feelings about the chaos that followed the success of "Patointeligencja", including a vulgar response to statements made by, among others, Jacek Kurski, Krystyna Pawłowicz, and Jarosław Jakimowicz regarding him and his father.

Another single announcing the album was the song "Kiss cam (podryw roku)", which was co-written with Mata by Szymon Frąckowiak, Mikołaj Vargas and Jakub Laszuk.
