FHLSF 

Fuck Her Like She's Fat -- Fucking a bitch like a freight train. Giving it everything you got, because when you're fuckin a fat bitch, you gotta jam it hard just to find the wet crease.

Understand though, you can fuck a skinny bitch like this too.

FLSFC 

Full Length Sub Frame Connector(s).

Structural Metal components normally consisting of square or rectangular tubing that is welded to a car's chassis to stiffen the unibody.

I had to put FLSFC's on my car so it would go around corners, preventing the chassis from twisting like a pretzel.
