HI boyyippee, welcome to the forum!
Okay, this is the best way I can describe it. When you borrow money from a company or obtain credit, you create an expectation of future income when the debt will be repaid. That's an asset of the corporation.
When a company 'charges-off' a loan, they're saying that they don't believe that they'll ever be able to collect the debt. So they 'write-off' the asset. It's an accounting entry that reduces their profits and taxes. This does not take away from the fact that you still owe them the money.
A charge off just 'zeros' out their ledgures for tax purposes, they write you off as a loss.
