Just compiling a list of British slang for you foreigners. Taken from this website: http://www.effingpot.com/slang.shtml. I’ve edited out the phrases that not many people use in the south, but if you want the full list it’s right here. Be warned though some of the terms are a bit out of date (as in only old people use them, for example “cor blimey”).
All right? - This is used a lot around London and the south to mean, “Hello, how are you”? You would say it to a complete stranger or someone you knew. The normal response would be for them to say “All right”? back to you. It is said as a question. Sometimes it might get expanded to “all right mate”? Mostly used by blue collar workers but also common among younger people.
Arse - This is a word that doesn’t seem to exist in America. It basically means the same as ass, but is much ruder. It is used in phrases like “pain in the arse” (a nuisance) or I “can’t be arsed” (I can’t be bothered) or you might hear something was “a half arsed attempt” meaning that it was not done properly.
Blatant - We use this word a lot to mean something is really obvious.
Bloody - One of the most useful swear words in English. Mostly used as an exclamation of surprise i.e. “bloody hell” or “bloody nora”. Something may be “bloody marvellous” or “bloody awful”. It is also used to emphasise almost anything, “you’re bloody mad”, “not bloody likely” and can also be used in the middle of other words to emphasise them. E.g. “Abso-bloody-lutely”! Americans should avoid saying “bloody” as they sound silly.
