Fachoina
Fachoina is a fun, loud, and annoying way to talk to people. You can use it for greetings, insults, or just to be a total pain in the neck.
Fachoina! I'm going to beat you up if you don't stop talking!
Fachoina! You're the worst friend ever!
Fachoina! I'm not going to finish my homework if you keep yelling.
