It simply means; Ok thanks
ie k, thx 4 ur help

"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.

Used to define a loss of a battle, game, or argument. Could be seen as an insult, as gg represents good game, no re represents no remake or redo, and k thx is alright, thanks. Most likely done to repress any counterattack from the opponent.

Shortening of kthxbye, which is in turn a shortened form 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 "God Be With You". "ktb" is the pinnacle of English's advancement, shortening "All correct, Thank you, God be with you." into three letters. Humanity is doomed. Obviously, it is used to end a conversation *fast* that you don't want to be in anymore.

Rebuttal to all arguments said politely and usually expressed at a time in which it makes zero logical sense.

This is an abbreviation for "Okay, i'm done fucking socializing with you now leave me the fuck alone before I leave golf-ball sized dents on your cranium."

Used commonly in internet conversations to politely end an argument.

Someone who cannot play counter-strike worth shit as well as loves having homosexual butt-love with the likes of Wally and AmF k thx
