"Forker" is a less known acronym for the word "Fucker". It is used when in the vicinity of strict adults, and at times when you don't feel like swearing.
"Kevin, you forker. Take the stupidlight!" "You are the biggest forker I have ever known."
When you forcefully shove a fork inside a females asshole multiple times until she loses a cup of blood. Collect the blood in the cup and use it as lubricant. Then pound the the females already damaged asshole until you are about to ejaculate. Then freeze the semen and then make her eat it the next morning with the same fork.
Placing the blade of a knife through the tines of a fork at a right angle. Reminiscent of a slingshot or catapult. Best when accompanied by shooting sound effects.
My son Jack entertained himself at the restaurant last night by making a knife forker with his silverware.
