So I came across this situation where it took me to go some taboo-like expressions to respond some igits(idiots), just like when we do in everyday Persian.
The expressions such as:
the 1st one: When you need to give them an answer like: "go nakhor/ghalat kardi"
the 2nd one: When it takes to go nuts like: "koft/maraz"
And the 3rd and last one : when things are so obvious that you can't say anything but to say: "man chi begam be to akhe?"
I hope you don't find the question offensive, I really need them anyways. These stuff are a part of every language though.
