acronym for Strictly Platonic Friend, used under these various conditions:
-the person has to actually be a CLOSE friend of an opposite sex
-your relationship has to resemble that of two romantic lovebirds' in some aspects
-yet the thought of you two as a couple makes both of you (or one of you) feel squeamish
-the person is conveniently your escort for all the shit-i-need-a-date events

Side panty fuck. Inserting his cock without taking the trouble to peel off your panties. Creates a slightly different feel. Ideally done when wearing a sexy pair of panties.
He didn't want to take the time to take off my panties so he just decided to go for an spf.

Seconds Per Frame.

Similar to FPS(Frames per Second), it indicate how much seconds it take to render one frame of video or a game.
Mainly used by: Gamers playing high end games on ancient hardware and amateur motion artist rendering videos in desktop PC.
Guy 1: Dude! I downloaded GTA 5 yesterday and it played like a charm at 60 FPS.
Guy 2: Ha! so pathetic, I used to play the same game at 186 SPF.
Guy 1: Woah! that's awesome!... wait... what!

Acronym for Smokey Pointer Finger. When you smoke a cigarette and your pointer finger has an inevitable aroma of smoke. Extremely difficult to remove with water, soap, hand sanitizer, or any other cleaning mechanism.
Not smoking is the only way to avoid SPF.
