Killersup used to say "sup" when greeting somone alot. He then just kinda found the killer thing and it sounded good. It was originally killersup7 but sombody had already taken it.
ahem hem* *starts dramatic voice* Well it all started, billions of years ago... There was a boy, his name was Matthew. What he didn't know was that he was going to go on a journey that might just change his life... I joke, I joke. It started off as an inside joke with my friends. My group of friends seem to argue at the most stupidest things that you would not believe,
"I'M TELLING YOU, IT'S PEANUT BUTTER IN THE SANDWICH!" "THEN WHY IS IT CRUNCHY?!" "PEANUT BUTTER IS ALWAYS CRUNCHY!"
Eventually I got sick of this arguing so whenever this happened and I got involved I would always say "I agree with you". You would not believe how disappointed they would get when I said it. I think they just argue for the sake of arguing =). Eventually I became known as the agreeing guy amongst my friends and it all just kept on building up from there.
I just needed an account name for a game in school and thought of 'cuffyruff' after seeing a chained up bulldog. After that didn't work, I just replaced the 'c' with a 'k', bringing me to where I am today.
