Basically, post thing YuGiOh/YuGiOh GX/YuGiOh 5ds character would never say.

I'll start.

Marik: They won't know how nice I am, using my Fairy deck!

then I got one

Yusei Fudo: Damn, Izayoi aki is one hot babe >_>

Kaiba: friendship is the best thing ever. Yugi, i just wanted to say i love you and that i don't care that you constantly kick my butt in the children's card game that has completely taken over my life. you are my best friend...well, maybe after Joey

Yugi: heart of the cards is for losers

Kaiba: Screw Obelisk the Tormentor. I've got Dark Magician!

Para Dox brothers

Para:don't you know that we love to ryhme
Dox: yes, we do it every day

may be lame but who cares

got a new one

Yami Yugi: Joey, I'm sorry, but, you duel as if you have the brain capacity of a retard !

Yugi: Screw the rules, I have money!

I guess there's two major reasons he wouldn't say that... For one, the obvious. Second, his grandfather's hospital bills have left him deep in debt. And since he gave all the Duelist Kingdom money to Joey, there's no way he could afford it. Even though I've never heard of LASIK Surgery costing $3,000,000.

i got one
Yugi:tea im not saying that your friendship speeches annoy me, but every time you make one i want to punch you in the throat :/

Joey: hey yugi i have an idea!... well play yugioh... but on motorbikes!
Yugi: joey... that is possibly the most stupidly retarded thing ive ever had the displeasure of hearing you say... ok!

I've got a new one

Pegasus: I'll steal your exodia cards and defeat you using my dino deck and there is no way you'll win because I'm using the millenium rod to see your hand

Yugi: Did you just summon a bunch of monsters in one turn?

Kaiba: Oh my apologies, it would appear I have accidentally made an illegal move according to the regulations. I forfeit the game as a result.

Have a swell day good sir.

Pegasus: with my mellenium eye i see that... what could he say that could be funny o.o i cant think of one

Serenity: Upon entering this duel, I heard you say that machines are more powerful than man. That's not true and you know it. Men and women alike operate the machines, which won't work without them. But you're dumb, aren't you, Nesbitt? If you weren't dumb, you could have stopped me from discarding, thus preventing me from activating my Deck Master special ability. Plus, you didn't count on that facedown card, did you? Oh, well, everyone learns from their mistakes, but you obviously don't. St. Joan, attack....

rebecca: i love kaiba

Tea: Yami Yugi is pretty hot..........if only his pants wasn't as tight as Micheal Jackson's own and stuck in the body of a 10 your old shrub for a boy

Kaiba: I think I'll donate my winnings from this tournament to charity. Nothing warms my heart like seeing all my hard-earned money going to aid elderly women with Alzheimer's.

got a new one

Shark: Yuma, sorry you're too pro for me

tea: I'm getting tired of this friendship thing. the smily face i drew on our hands is ugly just like my so called friends

chumley: lets run

Yami Bakura: I enjoy little kitties and looking at Marik sleep.

Tea: friendship sucks

Yugi: I wish i felt the pain of losing a duel

Shark: maybe, just maybe, I'm being too cruel and harsh to Yuma .....

Yusei: You can be my wingman anytime, Jaden
