The Straw Man?? Could be just referencing a straw buyer or straw borrower. Both are associated with fraudulent loan applications by misrepresentation and identity fraud. Being involved means your taking great risk on behalf of a friend or family member. And I don't mean co-signing a loan.
By US Banking definition:
A straw borrower is a term for an individual whose name, SSN, and credit history are used to hide the identity of the organizers of a for-profit loan fraud scheme. Additionally, Straw Buyers (commonly referred to as the Strawman) are also used in order to obtain a loan for a person who would not qualify for the loan, frequently a family member or a friend.
In for profit schemes, the straw buyer is usually compensated by the organizer for the use of his financial identity. While the straw borrower may have been lured into the transaction with the promise that he would not be liable for the loan payments, the straw is legally bound once the loan is obtained and will be responsible for making the payments.
This cryptic post made by the OP referencing strawman, most likely implies he possibly fronted for a loan on behalf of a friend or family member, who has not made the loan payments, and is possibly in default. But whose name is on the loan....it's the Strawman's name.
