Question

پررو میشه ؟! / روش زیاد میشه ؟!

Answer 1

For the second one i have come up with:
"He would get cheeky"
And for the first one i have no idea if " bite one's head off" can make any sense here, because i have not fully understood the persian meaning yet, since you can have such state of feeling out of surprise or when someone is talking a lot to you or explaining something a lot or when something is beyond your understanding which you can say " it is way over my head"
