give (someone) the length of (one's) tongue
To voice one's opinion, often in an aggressive or abusive way. I thought Paul was unhappy, but I did not expect him to lash out and give me the length of his tongue like that. I can't stand being around my mom when she starts giving us the length of her tongue.
