The extremely annoying one or two character text consisting of either "K" or "Ok" that one receives at or near the end of a text conversation, usually preceded by a informative or directive text. Hated universally for its lack of substance and often wasting valuable limited texts for those of us who are too poor to afford unlimited.
While texting:
"R u goin to the game 2mrw?"
"Yea everyone else is going"
"K"

"Will you go out with me?"
"No I think you are unattractive and stupid."
"K"

Teenager 1: Dude why didn't you text me back?
Teenager 2: You send me the K text you dumbass.
