shortening of "k thx bye". The K is short for OK, which is short for oll korrect, which is a facetious alteration of All Correct. thx is short for thanx which is a facetious alteration of thanks which is short for thank you. Bye is short for goodbye, which is an alteration of alteration of God be with you. "kthxbye" is the pinnacle of English's advancement, shortening "All correct, Thank you, God be with you." into seven lowercase letters. Humanity is doomed. Obviously, it is used to end a conversation *fast* that you don't want to be in anymore.
Whiny bitch: Here's your hamburger. Anyway, as I was saying about how bad my life is...

Other dude: Yum, burger. kthxbye. *leaves*

Whiny bitch: I have no friends. Wan wan wan.

1.) Form of the phrase "Ok, Thank you. Goodbye." Used exclusively on the internet, most commonly in cases where a person no longer wishes to continue a conversation.

2.) Same phrase, used to intensify an argument by making all who are involved angry at that person for using the already overused phrase.

Can be replaced by : kthnxbye, kthxownt
uber1337: France is ass soup. kthxbye.

"You can shut up now." Used mockingly in reference to people who, using stupid-looking internet shorthand, will say "k thx bye" ("okay, thanks, bye") when making a request on a message board or chatroom.
