Well, if you're still accepting these, here's mine:
Skin: Quint all the way! 
Name: Mamaluigi
Favourite Weapon: Sakugarne
[IntroStrings]
"Happy Creeper Happy Happy Yay YAY!"
"How can I help you King Dedede?"
"Hey Guys!"
"It's a brand new match!"
"That's Mamaluigi to you, Mario!"
[FragStrings]
"Oops! Did that hurt?"
"Oh, you weren't taking attention? Better luck next time, $player_killed !"
"SSSSsssss....BOOM!"
[KilledStrings]
"...I should get better!"
"Ow! That hurt!"
"I fell for hours!"
"Bah! Now I know how meatball feels."
[RoamingStrings]
"I'm old school, yeah, that's cool!"
"I'm an eight-bit sidescrolling fool!"
"Nintendo got it right! Not Sega. (They got Sonic right, though.)"
"I hope she made lotssa spaghetti!"
"And YOU'VE gotta help us!"
"If you need instructions on how to win this round, check out the enclosed instruction book."
[EnragedStrings]
"FFFFFFFFFFFUUUUUUUUU-"
"You dare not agree with Weegee?"
"I need a monster to clobber that there Kirby!"
"DOCTOR OCTAGONAPUS BWAAAAA-"
[WinStrings]
"Happy Happy Yay YAY! Happy!"
"Better luck next time!"
"I won? Yay!"
"Too bad everybody can't be a winner at the same time. Maybe later!"
[LoseStrings]
"I admit defeat..."
"I lost? Aww..."
"Nooo!"
"That was a fun game, though."
"Congrats!"
"Who won? Here is a hint: EVERYONE! Except for me, apparently."
"I lost, like always."
I thought I was the only one here who watches
Kirby: Right Back at Ya! 
You should also add the phrase
"That's what we do best at NME!" as another WinQuote.
Anyway, since I don't play online I won't accually join here,
but I have made a botchat for my class for Community Classes. If anyone's curious here it is:
[IntroStrings]
"Rawr."
"/me ghost data loading complete"
[FragStrings]
"Horray I got someone."
"Wait, I killed someone?"
"Yes, oh yes! Muwahahahahahahaha!!"
[KilledStrings]
"I felt that."
"Whoops!"
"Ow."
"/me c-is a cheater: god"
[RareRoamingStrings]
"Anyone tried Jelly World in Chaos Generator Upgraded? It makes exploring FUN."
"I hope no one's ckSparkmanc*, cqSnakemanc*, ctShadowmanc* or ckPharaohmanc*."
[RoamingStrings]
"Watch out, I can even fire a version of those cgQuickmanc* Beams."
"/me wanders around aimlessly"
"Since I have infinite ammo, I can blast the level geometry all I want."
"Since the real me dosen't play online, I serve as his ghost data instead!"
"Uhh..."
[EnragedStrings]
"cgNow you're making me hopping mad!!"
[WinStrings]
"I won! ... I cgMUSTc* be cheating!"
"Eh, it was an enjoyable game anyway."
[LoseStrings]
"Can we play MM2BUBX next?"
"You may have won this battle, $player_inlead, but THIS WAR ISN'T OVER!!"
"Eh, it was an enjoyable game anyway."
