Hi, being from Northern Ireland, I used to hear some gems eg:
That's a fine doorful of a woman/ man - Larger Lady/ Man.
She has a tongue that would clip a hedge - Gossip.
What would you expect out of a pig but a grunt? - Someone swearing.
That man would talk the teeth out of a saw - Chatterbox.
Plus dafter ones:
May you get all your wishes but one so you always have something to strive for.
Knowledge is knowing that a tomato is a fruit
Wisdom is not putting it in a fruit salad.
These are the ones that spring to mind but there are probaly hundreds.
Just One more:
He's got they eyes of a travelling rat - Obserrvant person.
