Your Understanding of "Snowballing"?

[David Dachtera]

Looking for folks' understanding of "snowballing".

From what I've found while Googling generally, it seems to be a hybrid of the "Debt Snowball" promoted by Dave Ramsey and "debt stacking" from Primerica in that it suggests to order debts by highest interest rate first, although the one with the highest rate may not be the highest outstanding balance. Thus, other balances may pay off before the one with the highest interest rate.

Your thoughts?
