You may be right about that, but here's a few from a Brit website including "bottle":
Slang Words
Below are a few slang words commonly used in Britain.
Bloke - man.
'John is a nice bloke to know.'
Botched - poor quality repairs.
'He made a botched job of fixing the television.'
Bottle - courage.
'He doesn't have the bottle to ask her.'
Cheesed Off - fed up
Chuck it down - to rain, often heavily.
'It is going to chuck it down soon.'
Chuffed - If you are chuffed, you are happy with something.
'I was chuffed to win a medal!'
Actually, that term is commonly used in the USA, too.
Off topic a bit, but sister-in-law lived in UK for a year. Prior to going, her huisband's company had a class on social customs and habits. It had a "translation list" and a list of what NOT to say.
"Fannie" (as in butt) was on the bad word list.
"Smartfannie" just does not do it like "smartass" LOL!
here's one I found: " A horse of good bottom means of good stamina, good foundation."
I've seen the phrase used in British books to refer to people as well.
So, I guess we're both right!
