naitan
Naitan is like a loud middle finger made of fists and grunts. You yell it like a savage when you punch someone or when you're too lazy to think of anything else to say.
I just got roasted by my homie. Naitan!
He dropped a beat and I said Naitan like it was my job.
I saw a kid eat a whole pizza. I said Naitan because I was too full to laugh.
