SFR 

S Fuckin' R

Used to describe a Nissan vehicle powered by one of Nissan's SR series motors, that has been modified in a particularly bogan way.

Can also be exclaimed in response to witnessing a particularly bogan event performed in a SR powered car.

Prevalent in Australia and New Zealand.

"Yeah I couln't be fucked sorting a DET swap so I just SFR'd a dirty +T"
"Keen for a hill mish G?" Yea G! SFR!"

Sfreepster 

One who is comfortable, and confident to speak freely when talking politics regardless of party affiliation.

Unlike some of the other political message boards, this message board sure does have a lot of sfreepsters posting in it.

DC SFRA 

Acronym for Washington DC Special Flight Restrictions Area. Excessive restrictions on General Aviation flight within 60 Nautical Miles of DC enacted temporarily after 9/11, then made permanent at the end of the Bush Administration. A useless bureaucratic circle jerk that inconveniences GA pilots while doing little to make us safer from terrorism.

Pilot #1: "Did you hear that the DC SFRA is now permanent?"
Pilot #2: "So some politicians got together and had a little circle jerk and decided that my routine GA flight is now a matter of national security based on an imagined threat?"
