Cách sử dụng
The expression "sell somebody/buy a pup" means to be tricked or deceived into buying something that turns out to be worthless or not as advertised. It can also be used to describe being fooled by a person's promises or claims. For example, if you buy a used car that the seller claimed was in perfect condition but then it breaks down immediately after you buy it, you could say "I feel like I bought a pup." Similarly, if someone makes promises to you that turn out to be false, you could say "I think that person may be trying to sell me a pup." This expression is often used in informal contexts and is commonly heard in the United Kingdom and Ireland.
