K 

Word commonly used in Sweden to express the fact that you couldn't care less about something. Often used to answer a question without answering it directly. Also used to kill conversations with people. If you find an online conversation with somebody to be boring or having an argument with anohter person online using K kills the conversation and will probably piss the other person off.

K directly translated means - I don't fucking care

Can also be used anywhere at any given time to express dissatisfaction with the conversation

- Do you like my new profile picture?
- yes.
- what is your favourite juice, I like pineapple juice the best.

- K
