5. You forget what FF is short for.

6. You get the most basic things about FFs mixed up. For example, you think FF4's main character is a Dragon Knight called Sephiroth who goes to fight an evil tree called Seifer who's actually working for a greater evil, a dancer girl called Setzer, who tries to create a time loop with the aid of a sphere hunter group known as Onion Kids.

7. When you see Mythril equipment and say "WTF? Tolkien where?"

8. You're totally confused when you see any of the following texts: kweh, wark, "Kupo!", Lali-Ho, Rally-Ho, Spoony Bard, "Ooh, soft!"

9. You don't write to this thread because of this kind of explanation: "I've got better things to do than talk about FFs in an FF message board!"

BTW For all who are suffering from feature #5, FF is short for Femmes Fatales Final Fantasy.
