12 British Sayings That Americans Don't Understand
http://finance.yahoo.com/news/12-british-sayings-americans-dont-214038733.html* Note the Brit word for Kitteh below "moggy"
4. “He’s such a chav.”
This is a pejorative epithet in Britain that’s used to described a specific kind of stereotype: A working-class person who is loud or brash and wears (usually fake) designer clothes — especially the classic Burberry check.
It is essentially the British version of “white trash” and should be used sparingly.
5. “You’ve thrown a spanner in the works.”
When you “put/throw a spanner in the works,” it means you’ve ruined a plan. A spanner is the word for a wrench in England, so it’s the British equivalent of “throwing a wrench in the plan.”
6. “Let’s have a chin-wag.”
Though fairly self-explanatory, having a “chinwag” (sometimes "chin-wag"
means that you’re having a brief chat with someone, usually associated with gossip. Just imagine a chin wagging up and down, and you’ll get the idea why.
7. “I’m chuffed to bits.”
If you’re “chuffed to bits,” it means that you’re really happy or thrilled about something. It’s also acceptable to say “chuffed” all on its own: “I’ve just scored free tickets to the Beyoncé concert, and I’m well chuffed!”
9. “My cat? She’s a moggy.”
REUTERS/Shamil Zhumatov This moggy is quite patriotic.
A “moggy” or “moggie” refers to an alley cat or a cat without a pedigree, but it is often used interchangeably as another word for “cat."

Jammy cow.
Knackered.
Shattered.
Plonk.
Was hoping for some more words, thanks 
Assuming these are findable on google..
Google "British idioms" and you'll find those and more . . .
Maybe not zimmer - which is sort of like our using "kleenex" for tissue. A zimmer frame is what we call a walker (for the elderly and/or infirm).
And congrats on your DU post milestone 
I hope you're not a vegetarian.
Of course, I learned that word (chav) from less-than highbrow movies. 
I had a friend who raised eyebrows in Herrod's when she was threatening to swat her daughter's fanny. Here, the phrase means "butt," however, in England, it's the front. Ooops.
My favorite is when the new British and Irish students would come for exchange programs, and noted we had a "Shag Club" next to the university. We'd get them all worked up, and take them in, only to confronted by several couples of old people dancing the state dance for South Carolina, the Shag. They always thought it was a sex club; their expressions were funny as hell. I wish he had camera phones then!
should be about kittehs.
