wtf is stadium size

The only appropriate size to have at a tailgate party on a humongous SUV with a pristine truck bed.

I'll leave this here...

bubbie <noun> <US> <informal> (chiefly Jewish) one's grandmother: as a child, I remember my bubbie singing Yiddish songs [as name] : on sabbath evenings, Bubbie would don a special kerchief. Etymology: from Yiddish bube "grandmother".

I didn't know until a minute ago that it's a American word. I wonder what affectionate Hebrew/Yiddish term Jewish Brits use.
