I remember me asking my new classmate on the very first school day of the 5th year of secondary school what her name was and recall her being a bit evasive at the time. The why of this evasiveness became all to clear to me later that day when she finally revealed, slightly red-faced, that her name was De Neucker which literally translates as "The f**ker" .
Anyway, both of us bursted into laughter and got along very well for the rest of the year.
