The original AZ name of the man who started this thread was ....
...Hungarian Nut...
This name is somewhat like mixing your metaphors.
The original phrase was 'Hungarian cinch'....as a result of the failed 1956
rebellion of Hungary against the USSR, a lot of street-wise Hungarian
refugees who were used to living outside the law immigrated to North
America....if you gambled with a Hungarian, you better have a back-up
plan....'cause you're gonna need some more dough real quick.
The term 'nuts' is used to denote when you got a cinch, Hungarian or
other-wise.
I've never seen a definition of this slang that convinces me that it didn't
come from an obscene ,or at best, a risque origin.
If you're in a street fight and you grab the guy by the nuts.....
...he be in a whole lotta trouble.
uh, did I mention?....this is my opinion
