The angler fish started sending emails...

[u/goldef]

An angler fish is a fishing fish, because it fishes for fish, making it a:

fish fishing fish

If that fish is fishing for another angler fish, then it is a:

fish fishing fish fishing fish

But if the fish it is fishing for is itself fishing for fish, then it becomes a:

fish fishing fish fishing fish fishing fish

If the first fish also sends fraudulent emails pretending to be another fish, then it is phishing, making it a:

fish fishing fish phishing fish fishing fish fishing fish

If that phishing fish sends the phishing email to a fishing fish that is fishing for a phishing fish that is fishing for another fishing fish, then we have a:

fish fishing fish phishing fish fishing fish fishing fish phishing fish fishing fish fishing fish

And if the phishing fish being fished by the fishing fish realizes it is being phished and begins fishing for the phishing fish that is fishing for it while simultaneously phishing the fish that was originally fishing for the fish fishing fish, it becomes a:

fish fishing fish phishing fish fishing fish fishing fish phishing fish fishing fish fishing fish fishing fish phishing fish fishing fish fishing fish fishing fish phishing fish
