So, the concept basically means, he can't say no if no-one asks, but is most of the time a bad explanation of the obvious duty of contract partners to act in each others interest.
The German definition according to their School of Law is that a contract is a mutal declaration of will and not that a contract is a framework setting rules of an agreement to do business.
The latter includes that contracts are limited in their topics, such as a signed paper to kill another human or work for free without any compensation is no contract, because that is no busness even so a mutual declaration of will. Two that want to end a life and two that want to be in a relationship have a mutual will finding a partner, but not in any business relationship.
Business is always a form of transaction in equal gain and cannot be abusive, especially in the USA that fought against slavery in its Civil War and against exploitation in its War of Independence.
A Declaration of Will is therefore a concept that Germans, the higher the education, can not intellectualy differentiate from a contract.
That paper there is not legally binding without a hearing, but also won't get you pretty much automatically into prison by any chance...
