An expression of indifference and disassociation capable of being used in almost all contexts. Exceptionally useful to dispense with ones own cock ups and your own or another's dissapointments. "Doesn't Fucking Matter"
George passes out paraletic on the couch and while he snores he pisses in his pants. On waking he realises his wife will discover his embarresing moment and sighs,"DFM".

Ollie fights for hours to land a Roland Ward marlin and in the death throws of the epic fishing battle George bumps his rod, the line snaps and the enormous fish escapes. George, to appease his concience, to hide his shame and to lighten Ollie's dissapointment exclains:- "DFM".
