Overlord Pandora's Actor scene Ger DUB

Instead of the "Wenn es meines Gottes Wille ist" Pandora's Actor said : "Ich schwöre euch mein Schöpfer Treue und Tapferkeit" with a trilling/rolled R.
It means something like "I promise you loyalty and bravery, my creator"(*)
Ainz answered with "Schluss jetzt ich dulde hier keinen geistigen Dünnpfiff, Bastard."
This means something like "STOP IT NOW, I won't tolerate any mental diarrhea here"
The Mental diarrhea is probably meant as reaction to Pandora's Actor intentionally trilling/rolling the R heavily, which in context would be him imitating Hitler's/Nazi speeches. (at least in Germany intentional heavy trilling/rolling of the r is sometimes associated with Nazi Germany)
((*)well I think promise is badly chosen the meaning of "schwöre" is more like swearing/making an oath but I somehow couldn't get it into an English sentence that didn't sound weird to me when using swear)
