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.
“Lappen” is also used as a fun but not overly offensive insult. Mainly for guys who act tough but really aren’t.
