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.
It’s called speaking more than one language.
That’s not what I mean. Like do you use any words that are pacific to that language. Like in German they have a pacific word for the day after tomorrow. I forgot what it was though.
Übermorgen. It exists in English too but isn’t really used: overmorrow.
