PSF 

Acronym for "Plastic Surgery Face", a condition that occurs when someone has so much plastic surgery done, that their face ends up looking like a half melted candle. A warning to those considering extensive plastic surgery, because they clearly haven't quite figured that shit out yet.

If you were the hot chick in an 80's music video, chances are you now have a severe case of PSF.

PSF 

To PSF someone is to pull an awesome prank on them, usually in the form of hilarious teamkilling in online games.

Originated from the Steam clan The PSF, "Petrol Station Flowers", and their crazy antics.

Did you just kill Baz with his own exploding barrel?
Yeah, classic PSF.

PSF is an acronym for "piece of shit faggot."

It is generally used when addressing a close friend as a term of endearment, in much the same fashion blacks stereotypically use racial slurs to express their friendship. Another similarity to the racial slurs parallel is that it is NOT acceptable to be outside a friendship circle and refer to someone within said circle as a "PSF."

The term "PSF" is often lengthened to its root "piece of shit faggot," depending upon the user and the situation at hand. When pressed for time or around someone not within the aforementioned circle, PSF becomes one's first choice. When not rushed and not bothered, the elongated term is the way to go.

Person 1: "What the fuck, man. That piece of shit faggot said he'd be here by now."

Person 2: "I know. Fuckin' PSF. Give him shit when he gets here."

PSF 

Acronym for Porn Star Finish. When a prostitute allows someone to cum on her face or body like a porn movie instead of cum inside her.

Most guys will do just about anything in exchange for an energetic, wet, sloppy blow job with a PSF.

PSF 

Pre-shit fart. A fart released shortly before taking a dump. Extraordinarily foul-smelling as a result of passing through a colon full of shit. Creates a warm or burning sensation in & around the anus when released.

"Dude, that PSF you just ripped was so nasty. Why don't you go to the bathroom and shit already?"
