"She's great fun, but she's a few sandwiches short of a picnic."

"Anorak" refers to someone who's a little bit geeky, with strong interests or expertise in a niche area.

Although it's more often used as a synonym for raincoat, an anorak is something slightly different in playground slang. This word probably originates from the "uncool" appearance of anorak coats and the people wearing them.

"Thomas is such an anorak when it comes to train trivia."

"Bagsy" is the British equivalent of calling "shotgun" or "dibs" when something, like the front seat of the car or food, is offered up to a group. School kids might call "bagsy" on items in their friends' pack lunches, like an apple or a cereal bar, that the friend isn't going to eat.

"Does anyone want thi—"

"Bagsy!"

"Bee's knees" refers to something at the "height of cool." This phrase became mainstream in the USA in the 1920s despite its British origins, but its popularity has dwindled since the turn of the century.

When first documented in the 18th century, the "bee's knees" referred to small or insignificant details. Since then, the phrase has evolved and now refers to something popular or cool.

"The Beatles are the bee's knees."

A "bender" is an extended period of drinking, usually in excess. Someone on a spree of excessive drinking and mischief is "on a bender." Benders can last over 24 hours, and so you might say that someone is on "a weekend bender," or a "three-day bender."

"I bumped into him towards the end of his four-day bender. He was a wreck."

A "bird" is an informal word for a girl or young woman.

While the phrase can be interpreted as misogynistic, it's still commonly used. It's usually used to describe a woman between the ages of 18 and 50, particularly one who is attractive.

"Look at that bird over there. She's fit."

To "pull a blinder" involves achieving something difficult faultlessly and skillfully. The phrase is most commonly used when the individual has been lucky and the person saying it is in disbelief that the first person has managed to pull it off.

"And did you see that equalizing goal in the last minute of injury time? He pulled a blinder there."

"Bloody" or "bleeding" is used to add emphasis to adjectives, similar to how "wicked" is used in New England. The origins of the word are widely disputed. Some believe it's derived from the Dutch word "blute," meaning "bare." Others believe the word is a contraction of the 17th-century phrase "by our lady," and is blasphemous.

This second theory has been disproved, however, by the slang's first documentation predating the widespread use of the phrase "by our lady."

Nowadays, "bloody" is used widely — it's even used in children's films such as "Harry Potter" — and is arguably one of the most quintessentially British words on the list.

"That was bloody good."

"Bob's your uncle" is the very British equivalent to "hey presto!" or "et voilá!" This phrase is often used to describe a process that seems more difficult than it actually is.

"Press down the clutch, put it into gear, then slowly ease off the clutch again. Bob's your uncle — you're driving!"

Something that is "bog-standard" is completely ordinary with no frills, embellishments, or add-ons. Its origins are somewhat unclear, but a "bog" is another word for a toilet in British slang, adding to the connotations that something "bog-standard" is unglamorous and unspecial.

"How was the hostel?" "Oh, nothing exciting to report. Just your bog-standard dorm, really."

The "boot" of a car is the trunk in American English. A popular pastime in the United Kingdom is attending or having your own "car boot sale," in which people usually sell knickknacks and old personal items out of the back of their cars.

A "botch job" is a repair job that's been completed in a hurry and will probably fall apart reasonably soon. A "botch job" can also refer to anything that's been done haphazardly, like a work assignment.

"Builder's tea" is the name of a strongly brewed cup of English breakfast tea with milk and sugar.

It's common courtesy to offer a laborer or builder working on your house a builder's tea while they're working — especially if they're working out in the cold. This is probably how the term came about.

"A bacon sandwich and a builder's tea. Now that's a proper breakfast."

"Codswallop" means something untrue, often made up for dramatic effect.

Although no one is completely sure of the word's origins, it could derive from the words "cod" and "wallop," which historically meant "imitation" and "beer" respectively — implying that "codswallop" is the kind of rubbish you make up when drunk.

"Oh, what a load of codswallop!"

"Cream crackered" is Cockney rhyming slang for "knackered," or incredibly tired.

The term probably came about because it rhymes with "knacker." A "knacker" was the person who slaughtered worn-out horses in the 19th and 20th centuries for their meat, hoofs, and hides. So, if you're "ready for the knacker's yard," you're exhausted beyond relief.

"This week's done me in already, and it's only Tuesday. I'm cream crackered."

"Dench" is an adjective used to advocate something that is impressive or agreeable. Dench is also the equivalent of "solid" or "cool" when used in response to someone else.

"I'm trying to flog my old sofa. Do you know anyone who might be interested?"

A "full Monty" refers to pursuing something to the absolute limits.

After "The Full Monty" film was released in 1997, there was some international confusion over the phrase, which was taken as a euphemism for stripping. However, "the full Monty" now usually refers to taking something as far as it can go, similar to "the whole nine yards."

"The full Monty" historically refers to an old tailor called Sir Montague Burton. Going "the full Monty" meant purchasing a full three-piece suit, a shirt, and all of the trimmings.

"Our Christmas dinner had everything from sprouts to Yorkshire puddings. If you're going to have a roast, have the full Monty!"

A "geezer" is a man who could be described as "suave" or "dapper," and is often suited and booted. Men from east London are also commonly referred to as "geezers," where the term is more interchangeable with "lad."

Geezer is thought to stem from the 15th century "guiser," which meant well-dressed.

"That guy's got such swagger — he's a proper geezer."

In the same vein, to "mug off" someone is to make a fool of them, usually by deceiving or cheating on them. The phrase is common on the hit British reality show "Love Island."

"He's going on a date with Amber? I feel so mugged off right now."

"You're mugging me off."

To "nick" something means to steal it. "The Nick" can refer to a prison. The origins of the phrase are largely debated online, however, it's believed that "to nick" as in to steal influenced the slang term for prison, as being imprisoned is similar to being "stolen" away.

"Shirty" could be used to describe someone who is short-tempered or irritated. The meaning of this slang has been debated at length.
