‘Fullz’, ‘clicking’ and ‘addys’: how teens talk about fraud

Kaf Okpattah reveals the language used by scammers, from ‘squares’ to ‘clicking’ and ‘mule herder’

Kaf Okpattah can speak the language of scammers. “Squares is one word which comes up a lot. That’s bank cards,” he says. “Fullz … that’s a person’s full financial information.”

In his new book, Scam Nation, he goes through more. “Clicking”, which means using stolen details to commit online crime; “addy”, which is used for the shipping address for fraudulently bought gear; and “mule herder”, meaning someone who recruits and manages people accepting stolen funds. Many of these are words he learned at school, he says.
