Bad back translation. The Czech title for “American Pie” is “Prci Prci Prcicky”. It sounds like a Czech children rhyme, but the word “prc(at)” means the same as English “Fu*k”. So this title translated back in English means something like “Fu*ky Fu*ky Fu*kity...”

Poor back translation. Eraser head is “Mazaci hlava” in Czech, this is a technical term. But in Czech is one word for “lubricate” and “erase” - “Mazat”

It is a Czech idiom for “break up”: “got a kick shoe”. Back translation is very poor.
