Kabaki
A buddy who's so close you'd punch a guy for them. Like they're family, but with more swearing and less chores.
My kabaki would die for me. Literally. I’ve seen him fight a guy over a pizza slice.
She’s my kabaki. If she says the sky is purple, I believe her and throw a tantrum.
He’s my kabaki. We’ve been best friends since third grade. He once brought me a sandwich during a math test.
