JK is shorthand for “just kidding” and has been a staple of text and chat since SMS days. It signals that a previous statement was a joke and shouldn’t be taken at face value.
On Gen Z platforms like TikTok and Discord, the related tone-tag “/j” is increasingly common. Both serve the same function: they protect the writer from being misread in a medium where tone of voice doesn’t carry.
JK is overwhelmingly lowercase, though “J/K” with a slash is a slightly older variant you’ll still see from millennials.
