Used in hospitals to define the state of someone who is not going to make it: "Totally Fucked, But Not Dead Yet!"
See that guy over there with the cracked pelvis and failed liver? He's T.F.Bundy...
Totally fucked but unfortunately not dead yet
A variant on FUBARBUNDY (fucked up beyond all recognition but unfortunately not dead yet). Used to describe people who are going to die but, so far, haven't.
The patient with a stroke, heart attack and pneumonia was T.F.BUNDY
