Spiv

Okay kiddo, so a "spiv" is someone who tries to make money by being sneaky or dishonest. They might try to sell you something that doesn't work or isn't really worth the money.

It's important to remember that not everyone is honest and trustworthy, so you should always be careful and ask for help from a grown-up if you're not sure about something. And if someone seems like a spiv, don't give them your money or trust them!
