Something you don't need to be going around threatening to stab somebody with. A fork is used for eating food, and a person should have no reason to think of a fork as anything more than an eating utensil.
The guy who uses a fork to eat and not to make threats is the guy who should be left alone. The guy who uses a fork as an example of something he might do is the guy who needs his fork taken from him until he knows how to use a goddamn fork, or when to joke and when not to.

An eating utensil with FOUR stabby prongs. (Not to get confused with a trident, a device with 3 prongs. Forks have 4 not 3. You do not eat with a trident, it is a godly weapon, not a fork.)

In a game of chess, the term "Fork" is used when a piece attacks 2 or more of the opponents pieces at the same time.

Quite often it's a Pawn or more frequently, a Knight that is responsible for executing a Fork.
Example 1:

White moved his Knight to square e6 placing black's King in check. Much to black's chagrin, his Queen was on f5 which also was a square the Knight was attacking when the check was placed. Thus creating a "Fork".

Because a Knight check can't be blocked, black had to move his King to get out of check, at which point the Knight captured black's Queen.

Example 2: White pushed his pawn to square e4 and as a result, attacked the black's Bishop on square d5 and Rook on square f5 simultaneously.
