KK can be interpreted as rude, especially when used in all caps. It can give off an aggressive or dismissive tone in certain contexts. However, when used in lowercase, it is generally seen as a casual and informal way of expressing agreement or acknowledgement.
The perception of rudeness also depends on the relationship between the sender and the receiver. If two friends are having a casual conversation and one responds with “kk,” it is usually understood as a simple affirmation or an indication of understanding.
However, in more formal or professional settings, using “kk” might be seen as unprofessional or disrespectful. It is generally advisable to use more complete words or phrases to show acknowledgement or agreement in these situations.
It’s important to consider the tone and context of the conversation before using “kk” or any other abbreviated response. Always be mindful of how your message might be interpreted by the recipient.
