A dumb response used by people who couldn't give two shits about what you're saying.
Person 1: My grandma just died.
Person 2: K

Girl: I really like you. I've liked you for a really long time. I think that you're funny and smart and cute and just an awesome peson. And I really hope that me telling you this doesn't ruin our friendship that we've had for 4 years.

Boy: K

Girl: K? I just poured my heart out to you and all you have to say is "K!"

the eleventh letter of the alphabet and the most annoying letter to receive by text message. which if someone texts you only saying "k" it usually means that person has no interest whatsoever and could really care less.
