Is it true that pointing at the palm of your hand with your forefinger is rude in Israel?

I read in a book about gestures that in Israel pointing at the palm of your hand with a forefinger has the meaning of 'The grass will grow on my hand before your words come true' ie Go f*** yourself. Is this true? And if not, has anyone come across this gesture anywhere else?

Actually no, pointing the third finger at you or upward is an insult (i.e. F*** you).
Reply:No such gesture exists in Israel.
Reply:Middle finger, not forefinger.
Reply:Of course it exists- I guess most people just aren't aware of it...


I have no idea what it has to do with grass, but it's basically the same as raising your middle finger at someone- just a nicer way of saying what you mean.





But yes, I've seen it and know it exists round here...
Reply:Never heard of that and I have lived here for years.
Reply:maybe u mean the gesture "wait"?
Reply:I have never seen the gesture or heard of that. No.


I do have a neighbor that will say as a curse to someone that he hates "May your cellphone stop working" but there is no hand gesture that goes with it LOL
