Similar versions of that phrase " walimy ..... na pizde." are pretty common in slavic countries (obviously the "turks" being replacable here). Its just a generic curse term that can be taken as "we're gonna fuck em up" (very loose translation). So that part is not racist.
But apparently turasow is a derogatory word for turks there which i cant really judge as thats some polish thing only. I dont know of that. But it wouldnt shock me. Balkan people for example use derogatory terms for different ethnicities or nationalities quite casually. Like its not even a big deal.
