Acronym for dirty fucking hippy. Often used with irony by liberal bloggers
to describe any person whose political views fall to the left of the American political/media establishment, and therefore are considered too shrill to be taken seriously by members of said establishment. Strangely, DFH does not appear to have a right-wing equivalent.
"Polls now show that 65% of Americans oppose the war in Iraq. Welcome to the DFH nation."
