I knew the Hebrew/Yiddish word mamzer ‘bastard’ was widespread, but this still surprised me:
Ebalus or Ebles Manzer or Manser (c. 870 – 935) was Count of Poitou and Duke of Aquitaine on two occasions: from 890 to 892; and then from 902 until his death in 935 (Poitou) and from 928 until 932 (Aquitaine).
Ebles was an illegitimate son of Ranulf II of Aquitaine. “Manzer” or “Mamzer” is a Hebrew word that means bastard, son of a gentile man and Jewish woman. It appears that Ebles did not mind his name, and his “illegitimacy became a part of his style.”
I guess if you’ve got a problematic nickname, that’s the way to deal with it.
