kk is one of those tiny social-media decisions that says more than the letters suggest. A single “k” can read as cold or dismissive, especially over text. Doubling it to “kk” softens the reply without adding any actual content.
It’s overwhelmingly used in casual DMs and texts between friends. It’s less common in work chats, where “k”, “kk” and “ok” all read differently depending on the relationship.
Almost always lowercase.
