What it means
Calling a guy king is a warm hype-up, crowning him for doing something admirable, kind or just being his best self: you made breakfast for everyone? King. Pure supportive energy.
Usage examples
"You stood up for your friend? King behaviour."
"Proud of you for going to therapy, king."
"You brought snacks for everyone and remembered my order too? King."
"Keep setting your boundaries, king. We love to see it."
Where it comes from
It comes straight from the literal word king, then got flipped into modern praise in online and spoken slang. Calling someone king gives them a playful little crown for being solid, kind, attractive, emotionally switched on, or just doing something that deserves gas-up energy.
