na fam
Na fam is when you tell your family member to go eat a pie made of their own poop and you mean no thank you.
My cousin said 'Na fam' after I gave him a used sock for his birthday.
My mom said 'Na fam' when I told her I was getting a tattoo of her face.
My brother yelled 'Na fam' when I said I was eating his favorite pizza slice.
