Question

if someone replies thanks with 'K' what does it mean? ​

Answer 1

Answer:

When you send a “k,” what you're saying is: I don't care what you've said and I don't want to talk to you anymore.

The only form of okay that can be used without misinterpretation resulting in the demise of a relationship is “kk” (and I’d argue “okay,” but we’ll get to that later). “Kk” is the closest to gotcha. It means message received, roger that. You’re on your way? Kk. Great, got it, we’re good. Pure acknowledgment. It’s cute and fast to type.

“Okay” is obviously the most professional way to type the word, and I will vouch that it is also safe to casually use in text messages. Some disagree that “okay” can sound sarcastic or stern, especially when paired with a period. Which isn’t wrong — sentences do invoke a more serious tone when there are periods involved. But the reason why okay is, well, okay, is because it’s the longest form of the word. You took the time to type out those additional two letters, and that counts for something.
