American English and British English have a bit of variations. Like -or and -our, -ize or -ise.

Loch is lake
Tattie is potato

Soda is "pop" in the Midwest

water fountain vs bubbler
sneakers vs tennis shoes

New York - Im gonna go to the store
Florida - Im finna go to the store

A lot, actually.

We have a lot in Northern Ireland, some of my favourites are:

Craic
Banjaxed
Ratten
Mucker
Eejit
Poke
Boke
Baltic
Oul doll
Big lad
Well, 'bout ye
How's she cuttin'?
Aye
Our blade
Caul
Craitur
Dander
Dead-on
Lock'a
Scundered
Skite
Tae
Weean
Whisht

I'm not putting all of them down but these are the words and phrases that people (myself included) in Northern Ireland use most of the time.

Soda = Pop
Winter Hat = Tuque
Bathroom = Washroom

Omg It sounds way cuter.

in the UK the plural "you" is sometimes "you lot"
in the USA it's either "you guys", "y'all", "yous/e", "you all", "yous/e guys", "yinz/s", etc
in jamaica it's "unu" (patois)

regional plural "you"s are interesting and plentiful, actually

Here in NI, we usually use 'yous' or 'yousuns' as the plural of you, I don't know why we do this though.
