It would be funny if some announcer started calling a play action pass a "flea flicker".... and stupid as well, same with the halfback option.
I'm sure none of us would think of either that way, but they are by the broadest definition.
What about a play where the QB tosses to a WR coming around who then throws a lateral back to the QB, or throws downfield to a QB? Made to look like a running play but isn't, not a FF to me at all. I'll stick with the narrow definition.
On a separate topic, I asked a former ATL Falcon how many words would be used in a typical play called in a huddle and he said about 6 or 7, real quick, he gave me a few examples. And he said it was work to learn a new playbook when you changed teams or OCs, but they practice so much it comes to them and they learn to listen for the key words that apply to them. This was Brian Finneran who played at Villanova.
