"Meet the Parents" star Teri Polo has royally Focked herself -- at least in the money department -- because TMZ has learned ... she just went belly up.
Teri filed for Chapter 11 bankruptcy last week, claiming she's buried in nearly a million dollars of debt -- most of which she owes to the IRS.
Teri claims she owes roughly $772,000 in back taxes and more than $36,000 in credit card debt.
She also says her landlord's going after her for $30,000 after she allegedly left an old apartment covered in dog crap and urine.
Bankruptcy ... you can't milk a cat, but you can milk the system.
