The term "paper route" can refer to two different things, one of which is a legitimate job and the other is a term used in criminal activity.

• Legitimate paper route: A paper route is a job where a person delivers newspapers to customers on a regular basis. This job is usually done by children or teenagers, and it can be a good way to earn some extra money.

• Criminal paper route: "Paper route money" is a term used to describe money that is left in secret places so people don’t get caught with it. This is also known as a "dead drop," where two individuals can exchange money or items in a secret location unlikely to be found by anyone else. Paper route money usually refers to nefarious activity, particularly those involved in criminal activity or drug deals.

It is important to note that the term "paper route" can also refer to a place where a dealer sells drugs from, according to Urban Dictionary.

In summary, "paper route" can refer to a legitimate job of delivering newspapers or a term used in criminal activity to describe money left in secret places for illegal transactions.
