Concessions puts together various declarations of victory, amusingly-captioned pictures, and other internet retorts and unspecific mockeries of mine. Most of them I did way back for the sake of amusement; when other people shared found pics, I'd make my own. Ironically I've only used a few once or twice myself, since I usually go to forums that either look down on direct insults or expect an actual debate in addition. Some of them still amuse me, though.

"Oooh, a *semantics* debate!"
A fun one I've used a couple times, but usually if I bother sticking with a full-blown debate it's not with a totally dishonest moron, so rarely do I have to debate personal definitions to a painfull degree. This one's sarcasm and audacity is what I still find funny (or maybe it's the rounded lavender letters).

Angelfire Image
No, it is not an image hosted by Angelfire, I did get a real host. It's almost as amusing how many people assume it's a normal broken direct link and don't read the text. ;-P

"Pwned" (Ass-Hazing)
I ran accross this image a long time back and had trouble looking for it again (I wasn't really ever in the mood to simply type 'big ass-spanking' or paddle butt smack' into Google), but the sight of some poor sap's ass pratically exploding with ripples on contact on the exact moment the photo was taken left a memorably amusing though in my mind. Anyhow, the copy I finally saw again was actually included incredibly lame and poorly-placed small text all over, so I had to edit it out (including the back of the hazer's shirt. Or maybe it's not a hazing actually; it could just some sex party with all men, hard to tell). I think big red 'pwn3d' typewriter text conveys ownage and humiliation fairly well.

Interrupting Fantasy
I'm pretty sure I used this once, and I'm pretty sure the target was not happy. In fact I probably sould use this one more often; it sums up a lot more than could be said with words, and could really diffuse a relevant situation. The text doesn't look nearly nearly as good as I wanted them (too thick and the font is off), but it goes nicely with that great picture of Tench and Ryoko.

Jinroh "Shut The Fuck Up"
A resized version of an early piece, the original was unmanagably large and therefore I avoided using it except in etreme cases of trolls or wackos (you better be sure as hell not to screw up the forum formatting if you're going to decry your opponent's incompetence). I dunno, I've gotten a lot of good remarks about it, but I'm kind of in the thought that its self-professed intolerance loses validity (a troll will proclaim presecution even if you're completely fair, and if they're that dishonest about how the rules have been applied to them you might as well go ahead and ban them). Oh well, maybe I just like the idea of the picture more than its actual usability.

Ryo-Ohki Says You're A Twat
Never found anyone worth looking up a URL and wasting an image link for to use on, but good gravy, does it always make me laugh. To see something so cute so happily exclaim "You're a fucking twat!" in orange and blue party text is just something else.

Oh My Goddess "Concession Accepted"
Roffle, burninated. :-P. This is yet another early-but-popular image, I think most of the work I put into this one was taking the screen capture itself. Fortunately I like to put a lot more effort even into quick projects these days.

"Do I Smell Spam?"
Yes, Wayne. Yes you do.

Riding Band Wagons
Now these two I've used quite a bit recently. I almost considered writing 'bandwagon' somewhere on them, but I figure it'd only be helping the kind of people who didn't need to understand; if they could see why I'd post wagon images when they're sucking up, I wouldn't be insulting them, now would I? ;-P
