k

Back in the day, you had to make sure your message was worth it. With the age of instantaneous communication, we've definitely devalued single messages.

And "you're mean" begins with "y," as in "Y R U SO MEANNNNN OMG"

This particular auto correct kicks in after the third or fourth straight "cool."

I DID NOT WAKE UP TO BE REMINDED OF POTASSIUM.

K? K.

J/K, and by J/K I mean "just kidding," and by "just kidding" I mean that I have nothing but withering disrespect for you and intend to turn every attempt you make at interacting with me an exercise in trolling the living daylights out of you, and by "trolling" I mean pissing you off.

I bet you responded all nonchalantly with a single "k," too.
