k00l
K00l is just cool written in a weird way, like a kid who thinks they're smart and tries to be cool but fails at it.
My friend tried to be k00l by typing in leet, but it just looked stupid.
He said he's k00l because he knows what leet is, but I don't even know what that means.
I asked my teacher what k00l means, and she said it's just cool, but I'm still confused.
