Arabic for
mad. Also a very popular
swear word in
Israel. The meaning in
Hebrew slang is not exactly the same as the
English '
maniac'. It is reserved for someone that you really don't
like.
For example, if you have a discussion with someone and you don't agree with what they have to say, you can say "Shtok, ya manyak!"
That's probably what happens in the peace talks between the Israelis and the Palestinians.
