never (you) mind (something)
Don't worry or bother about something. Never you mind his remarks—he's just jealous. I want to get this for your kids, never mind the cost!
never you mind
Do not worry or fret over this; you do not need to concern yourself with this; this is not any of your business. John: "Hey honey, what are you wrapping in there?" Amy: "Never you mind! It's not for prying eyes." Janet: "How are you going to convince the boss to give us the week off?" Dan: "Never you mind. I have my methods."
