F H B - is what my dad would say at the dinner table if we had guests. It's short for "Family hold back" and was the instruction to allow the guests to help themselves to vegetables, gravy etc first. I seem to remember him explaining that it's what his own Da used to say, and so I've tried to get my own children to use it too.

"Sufficient unto the day thereof" is what my paternal grandmother used to say when she'd had enough to eat, misquoting Matthew 6:34.

You'd make a better door than a window. said when one was between parent and what they wanted to look at.

An overhang from wartime, when someone was going out, my mother (or her sister) would call Don't forget your gas mask! Oh! I see you're wearing it.

Wood! meaning "shut the door" - (short form of "Oi! Put that piece of wood in the hole in the wall")

S'nuff ter blaah yer lugs off My mum, a Geordie, uses this when it's rather windy. As a result, so do I.

"You don't want to go stuffing your face with food every five-and-twenty minutes!" said to my teenaged or 20-something father and and a small bunch of his mates after they'd spent a very long time - possibly a day and half a night - on some hunting/shooting/fishing mission, which involved some mishap of getting lost. On returning to civilisation they were hungry, but whoever it was they had arranged to meet that evening had been well-fed that day and didn't feel the need to dine. It was repeated by my late Daddy whenever we complained about being hungry.

She's some kinda lady. Delivered derisively to mean quite the opposite after Mom had witnessed something very unlady-like indeed. :-)
