Nie Mam Nic

Around my house I say "nie mam nic" - a Polish phrase from my Grandma. I use it, as she did, to mean "enough/stop it/done/be quiet/knock it off." Junie objects to this usage. 

"It means 'I have nothing' Dad, not ---- and ----."

Me: "It's an idiom. I'll use it any dang way I please."

Now, Marta M Sta-  can educate me as to whether that's strictly true or not, but regardless, as far as the discussion goes little girl, its nie mam nic.
