I like to learn about words from around the world and use them in my speech. I have a particular love for British words. I just love words like spiv, nod, wasteman, barmy, slapper, bruv, lezza, shafted, nonce, junkie, bint, smackhead, nutter, slag, breve, chav, squiffy, slaphead, looney/loon, bender, and dosh.
I love “what a load of rubbish” describing something unfair or dishonest.
Sometimes I’ll throw out an “I say, old chap” for fun.
