you can view things the way you want or use terms the way you want. I also don't put much stock in Wikipedia but here is what they say about the Forward Lateral: There is such a term and it is against the rules.

You can use terms the way you want. That is true. If you wish to call an illegal forward pass a "forward lateral," you have that right. However, the term does not exist in the NFHS, NCAA or NFL rule books.
In the rule books, words have very specific definitions. Officials must know these definitions in order to properly rule on a play. I'm not trying to be a dick. I'm just trying to clear up misconceptions about the rules when I see them on here. "The ground cannot cause a fumble" is a popular one. Saying there is any kind of difference between an overhand pass and a shuffle pass is another.
A forward pass is any ball that is thrown so that it travels towards the opponent's goal line. It is legal only if thrown by Team A (the offense at the snap) in or behind the neutral zone prior to a change of possession, before any ball carrier has crossed the neutral zone and is the first forward pass thrown during that down.
You said there was a difference between a forward lateral and an illegal forward pass. There is not. One is a fan term that has no meaning to officials. The other is a foul in the rule book. And it is a foul regardless of the manner in which it was thrown.
