I'm not sure if these have been stated before, as these are a lot of pages to wade through at 2 in the morning. But I've enjoyed what I have read, and laughed at some of them. I'm also not sure my entries are all fallacies, per se, (exactly what you're looking for in this thread). But they can certainly be false assumptions of a kind.
Ad Infinitum, or No Mas/No Mas: If I argue until the other guy gives up or has no more time to continue then I win by virtue of the fact that he ran out of time or interest. With practice and nothing better to do I can eventually win all of my arguments in this way.
Non, et Non: No reasoning on your part will force me to reconsider the validity of my argument (or yours), and conceding any part of your argument in some way endangers all of my argument. Therefore nothing you say will endanger my line of non-reasoning. There's just no reason for it.
Argumentum Bonum: I like a good argument, therefore I will find something to argue about your point, even if it is tangential, or if I am the only one reading it this way. If I can't find something to disagree with, then I'll invent something.
Expertus Maximus: I've won other similar arguments, therefore I've won this one... when will you learn?
Squirtus Maximus: Watch my emotions torrent in a squirty stream of illogic which is nonetheless devastatingly passionate. Therefore, I win. I just feel more deeply about it than you do.
Ass-umptus Maximus: You didn't really say this (or that), but I'm assuming it's obviously what you meant, and even if I could easily verify your real point by asking you a few simple questions, it's just more fun to argue my assumption than the exactness of your point. Assumptions are fun after all!
When you Win/Wins: I won this argument on the basis of the fact that I decided I won, therefore, you win by virtue of the fact that you were able to bask in the glory of my winitude. It's a win/win for everyone, you pathetic Loser!
Misunderstandus Inexplicipus: For some inexplicable reason I cannot yet fathom your point, and so therefore, since you didn't make it plain enough, your reasoning is naturally faulty. (You failed to communicate in such a way that I could easily understand you, therefore, you must be an idiot!)
Tourette's Argument (from design): What a $*!+-faced @$$ u must be in real life. You must be some kinda moron who is hated by everyone you know, so, you lose! (This is a big problem on the internet since it has been statistically proven that users of the internet suffer from Tourette's Argument Fallacy at a rate of 1000 times that of the general population. Reason's unknown, but probably deducible.)
Familiaris Internetus (or, I Know You Through the Aether): I know all about you and your kind that I need to know through the internet. Therefore I know you and what you really meant, and who and what you really are. See, I'm brilliant like that.
Meekus Squeakus: I think this way, therefore everyone thinks this way, and if they don't then they obviously haven't had the advantage of thinking like me.
Politicus Correctimus: Every argument in the end is surely a political one, and trust me, my politics are far more evolved and sophisticated than yours. Therefore, I win!
Wishful Blissful: My one wish is that you realize how stupid you are, cause if you realized how stupid you are then you'd realize how stupid I think you are. And then we could share that in common. (Translation: you're not nearly as smart as I obviously think I am, so when are you gonna figure that out already? What, do I just have to keep telling ya over and over again.)
Invisiblus Ironicus: You and I both understand the irony of what I am saying, but if I close my eyes hard enough, it never happened, and so you won't notice either.
Singularis Unum (aka, My Psychic Crush on Myself): I'm the only one who really understands the brilliance of what I am saying. So no matter how fragile my position may be, secretly, and deep inside, I've already won in my own mind. If only more people could understand this instinctively, it would be a far better world.
Invictus Indubilus: The point of every argument is to vanquish the enemy, to hear the lamentations of the women, to curse the dark ignorance of the foe, to conquer all opposition and doubt, to lay low the adversary. We do not debate to discover truth, we argue to crush the fool who dares to question me! (The internet is not for fun, or a place to pursue your interests, or to have stimulating, fruitful debates, it is a place to prove what a fool the other guy must be for messin with me.)
The Masterbaiter: Yes, deep down I understand exactly what you mean and probably agree, but let me rebait your argument in a totally different way so as to draw in someone else who I know will open this thing up like unholy hell on a hotplate.
Terminus Idioticus: Look there you idiot, you misused or misspelled a term in some way. Therefore everything else you say is stupid! Therefore I win, you maroon!
Victory by Fanbase: The obvious truth of my argument is proven by the fact of my dedicated fanbase. If you had a fanbase then it could fight mine, but you don't, so, you lose again!
Web of Allusions: Look, I've said this on the internet (or seen it said) a thousand times. By now it must be true!
