You're so MEAN to Seymour! He's not a pedophile! He's the coolest FF villain ever and/or I want to have his babies!
See above. Also, it's good to understand the concept of exaggerating for humor. Especially if you hang around here. Christ.

I think I am SPESHUL and SUBVERSIVE because I like a character you don't! So I'm going to show up on your forums and make a huge ass of myself, explaining in detail why my opinion is correct and mentioning my OMGSODIFFERENT opinion in every single post I make on the boards!
Okay. Here's the thing. We don't give a flying fuck if you have a different opinion on a character or a game. There are -- gasp! -- people on the boards who like Tidus/Wakka/Seymour/whoever. You are not special. But if you annoy the shit out of us by following through on your little crusade to be a dumbass on the boards, you will most likely get banned.

What are some of those weird acronyms you use, like CASC?
I use acronyms to keep track of some of the trends in Final Fantasy X. Here is a list:

CASC = Current Ass Shot Count. For keeping track of the number of times that someone's ass is in the foreground of the screen.
TSC = Tidus Story Count. For keeping track of the number of times that someone refers to it being Tidus' story.

Note: I kind of dropped these acronyms after a while because, as I learned the hard way, it's really, really tough to keep track of things that happen almost constantly.
