According to the "Additional Readings: Chapter 7 - Credit Counseling, Debtor Education Information, and the Means Test"

in Module 14:

A debtor that does not pass the bankruptcy means test may choose to file for Chapter 7 anyway. In all likelihood, a motion will be made to dismiss the case or convert it to a Chapter 13 bankruptcy. The debtor can defend the motion by establishing the presence of "special circumstances," such as recent unemployment, unusually high rent, or a serious _________ condition.
