klootzak (Dutch)
Where does "klootzak" come from?
The Dutch term 'klootzak' is a blunt compound of 'kloot', meaning a ball or lump, and 'zak', meaning a sack or bag. While 'kloot' traces back to Proto-Germanic roots describing something balled up or clotted, the word 'zak' has a vast history as a Mediterranean loanword eventually arriving from the Latin 'saccus'. Together, they evolved from a literal description of a scrotum into a common, vulgar Dutch epithet used to insult a man.
