When I lived in Vermont, they used to call a lake a pond. They also end most sentences with, "yep, yep."

The antlers thing is because the deer or elk has shed their antlers.

My Mom used to say, when I was acting up, "I'll jerk a knot in your tail!"

Around here, when an older person discovers something they've been looking for was right in front of them all along, they say "if that had been a bear, it would have bitten me" - or, in the old East Anglian accent which, sadly, will be gone forever within a decade, "if tha' wurra burr, it wudda bit me".

I'd never heard it anywhere else in the UK and, as there have been no bears here for a thousand years, it seemed rather a peculiar saying. Then, one day, I happened to mention it to a Dutch friend who said she'd heard it in the Netherlands - so it may have been brought over with the Dutch drainages engineers who came to drain the Fens from the 1630s onwards.

"Keep Portland Weird" is a local mantra (Portland, OR). We like tha t is is a bit off beat.

You belong here is like a one legged man entering an ass kicking contest.

Central NY: On Accident

My father, from Oklahoma, used to describe heavy rain as "Like a cow pissing on a flat rock." Another was "Don't get your tit in a ringer."

Thankfully I was born and raised in California

The bees knees or dogs bollocks for something good.

Deep "New Yawk" accents. Even though I consider myself a New Yorker, growing up in New Jersey I never actually developed one, though I can slide into it easily, especially when stressed. My mother's accent was very prominent -- for example, one of her favorite TV shows was "Lor 'n' Awda," she always loved her "cawfee," and she never left the house without her "pockabook."

Ha there are so many, where do I start? The one that irks me most is the word we've which translated turns into where've ?, another one is mayor turns into mare ? and many words are shortened with the letters ....ie. For eg. photo is a photie, a tradesman is a tradie, breakfaat is brekkie. I could go on and on and on..........

None of those would be strange to hear in my part of the Appalachians either. There are oodles of colorful southern sayings around here, so much apart of my speech that I can't even think of a way to dilineate and recount them in my memory. I'll have to spend a week thinking about it to notice em in practice and make a mental list. The last time I surprised someone with a saying they hadn't heard before it was "I gotta eat somethin, I'm about to fall through my ass n hang myself."

Also I think an antler shed is called that because they literally shed their antlers and regrow them every year. That ones not so much an expressive nickname as it is just the verb for what they did.

We have a very local one here in the north east of the UK. "Put th'a wood in't hole." Meaning, do not leave the door open.

"You can't have your cake and eat it. " I could never understand that one as a child since it sounded so obvious it was surely a tautology. It was only when I grew older and realized that it was an answer to people with a excessively high sense of entitlement that it became clear.

In portuguese we have a word that literally translates as un-ass.
It means don't worry and have fun. Like "I drank a lot yesterday and un-assed myself"

As a native rural southerner, I enjoy very descriptive southern exxpressions like It come a tosad=strangler" ( rained very heavily), or ":as useless as the tits on a boar hog>"

I grew up in central Wahington, I have heard it before.

The most bizarre one I have heard, "I haven't had this much fun since the hogs ate my little brother".

Always drink upstream from the herd
