"Off the back of a lorry" is a phrase that means something has been obtained illegally or without paying for it. In the UK, it is often used to describe goods that are sold at a cheap price, but are likely to have been stolen or acquired illegitimately. For example, if someone offers to sell you a new TV at a very low price, you might say "I'm not interested in buying something off the back of a lorry". It's important to be careful when buying things cheaply, as it could be illegal or of poor quality.
