Nice. Long ago I once had a Hungarian friend who told me great terms like lofasz and puncifüst. I hope they are still in circulation.
lófasz (horse dick) i use on a daily basis

one of my favorites is "lankadt lófasz" (limp horse dick), which i often use to describe soulless, weak performances, either by footballers (think rabiot's juve career) or by anyone who failed to provide an effort.
puncifüst i never heard, might still be some regional word. picsafüst (literal translation is "cunt smoke", means "nothing" or "not a biggie") is pretty common though
