Going ape-shit
I have no idea regarding the etymology...
On a more positive note, Farsi can be quite dramatic and poetic even when it cones to everyday expressions.
So you might hear "ghorbunet beram" 10 times a day, especially when there are children around. It literally means "I would sacrifice myself/die for you" but translates as "I love you (so much" or "you are so lovely / sweet" :)
