There we are then.
In South Wales a lot of people say "There we are then" when an argument has finished along the lines of "Don't bother talking to me anymore." The reality was realised when someone said take the first letter from each word.

Talking of Twat, when I moved to Manchester, a local said he knew a guy they were going to take out that night and "give a right good twatting." My innocent mind was thinking a twat was nothing more then female genitalia, so they must be taking him out to get him laid... Lucky bloke.

New word i heard yesterday - "mufty"
it sounds really rude to me, and soemone said that the kids at some school were having a "mufty day".

i thought it refered to soem naked frollicing - but apparently it means you don't wear uniform in aid of charity or something..

crap innit, what a waste of a good word

My favourite is
GUNT - When a womens belly is tucked in below the wastline, so it looks like she has a gut there instead of a vag.

i.e "Natalie Curtis's gunt was always a popular discussion at the dinner table"
or
"CHAG - Curtis Has A Gunt"

Nowadays she is skinnier, but we still call her CHAG "Curtis Hasn't A Gunt"

It's not actually being used at the moment
but a friend and I tried to get people to use 'Moist' as a swear word, due to the revolting images it conjures up when used in any other context but that of your grandma's cakes.

Moist B*stard = sweaty
Moist F*cker = Hugh Hefner?!
Moist C**t = bleurgh!

The east coast version...
of "getting off at Paisley" is "getting off at Haymarket", which is the station before Edinburgh Waverley.

This is a bit of 'drunken rhyming slang'
'buns' short for 'bunsen burner' or 'nice little earner'. Perfect for all (both) those occasions that something goes your way.

my friend's brother came up with
"poped"
to mean, basically, messed up in some way.. way too baked, or sick, that kind of thing.. because the pope is so shaky and messed up all the time, i guess.
he's so poped.

god damn!
I currently live in Tennessee, U.S.A. and people here like to get their point across by drawing comparisons to god. As in "I swear, he is richer than god!" or "yeah, he is like more ripped than god."

I'm not really on a first name basis with god, but I'm pretty sure he would take umbrage at these comparisons.

Zomig
A "zomig" is a person with no knowledge or skill who uses Frontpage and clipart to make websites, named after a pen I found with "Zomig" on in the computer room in school and my friend scrawled "Frontpage sucks" with it all over the "Web Design" handouts that were lying around.

Then we found out Zomig is some form of nasal spray type drug.

Not the best but it's regional...
In the not-so-very-great MN, we have the Hat People. as in those dudes who drive with a plastic asshat (A plastic-surgeryed britney wannabe) at their side and a college hat over their eyes. They are mostly drunk and make great target practice with paintballs.

quite a common sight here in the u.ass.a,really....
whenever anybody is wandering about with their pants headed north(due to tight clothing or an ass like a tanker truck,it doesn't matter),they're 'having an ass snack'.
scary thing is,my mum's the one who thought of the phrase!
my circle of friends refers to bad luck as 'getting the cheese grater' due to a cushionless chair in our long-ago arts class,the seat of which resembled a cheese grater both visually and phisically.if you were late,you got the cheese grater.people stare at us like we're mad when we say it.

High School Slang Is The Best
At my high school, we considered drawing up a new dictionary. Most of the slang was based on people, but a few were just the result of the general insanity of high school. A sampling:

1. "Silence cheese": phrase meaning "shut the hell up". Taken from a teacher with a speech impediment.

2. "Silencio queso": the Spanish form of "Silence cheese"; it became much more popular than it's predecesor.

3. "Gweggish": an adj. Taken from a kid named Greg, who's mother had a heavy West Virginian accent, and pronounced his name "Gweg". Usually the perpetrator of most of the stupid (hilarious) actions at our school (Such as riding down the steps in the top of a garbage bin or drinking a bottle of tobasco sauce or giving me a scar with a hot glue gun). Means to act in a silly or otherwise crazy in manner.

Use: "Stop being Gweggish, we've got work to do."

4. "___-Style": to do something in the manner of, using someone's last name, and then doing something that they might do.

Use: "I'm going Mr. Kinner-Style and pulling my pants up to my armpits."

5. "Ohhhhhhhh!": Celebratory proclamation. Hand gesture (consisting of what one might do with their hands when talking about a woman with huge... tracts of land) also desired when "Ohhhhhhhh!" is said. Origin comes from a spontaneous soccer goal celebration.

Use: "I just got an A on that exam... OHHHHHHHH!!!"

6. The shortening of words also played a big factor in the slang. Not sure of the origin, but it could be applied to virtually everything.

Use: "I got way too many demerits, so now I've got a detench."

7. "The Bills": Slang name for a very large family, called the Williams, all of whom attended the school, including a teacher.

Use: "I've got a party going on Saturday, so I'm going to invite some of The Bills over."

There are other, more minor phrases, but they have been lost to the ages...

Edit:
8. "Risk it all": Comes from a lunchtime game in which one unlucky soul was chosen to carry as many as 40+ the lunch trays to the bin. This unlucky fellow was chosen by several rounds of "Rock, Paper, Scissors". The phrase "Risk it All" was also applied to any situation involving chance.

Use: "I thought he might play it safe and ask Sarah out, but it looks like he's going to Risk it All and try to see if Jan wants to go with him."
