In a small region of Germany, in the palatinate forest, „käftz“ stands for the
asshole of a human being.
But in various
hood slangs you can replace any other word which sounds a bit
like „käftz“ oder „käftzen“ in every sentence you can imagine.
Hey Simon, please dont always show me your käftz when your
drunk.
Hey Mum, our
fridge is all empty. We really have to „einkäftz“ some
stuff.
Last night we had a huge Käftzerei in the club with some cunts!
