This is a common name for a small scam around the urban areas of Canada, Sao Paolo, Brazil and certain parts of the Caribbean (namely Jamaica). This is a low level hustle where the scammer puts a lot of effort for a very small reward, usually under $10 or equivalent in goods. Due to the small amounts taken the person (usually a friend or acquaintance) being scammed doesn't even realize they have been fooled until much later.
