k3k
k3k is when you laugh so hard you might explode. It's like the nuclear version of kek and lol. People use it when they're too busy laughing to think straight.
My dog ate my homework and I k3k'd so hard I dropped my phone in the toilet.
She told the joke about the math teacher and I k3k'd until my neighbor came out to check if I was okay.
He texted me 'I just failed my math test' and I k3k'd so hard I cried.
