Gaffarena
A guy who ran away from dad and left a disaster in Maltese. People use it when they're furious.
You're a gaffarena, I'm surprised your dog doesn't talk back to you.
He's a gaffarena, I bet he got lost on the way to the store.
Don't call me a gaffarena, I'll steal your lunch money and eat it in front of the whole class.
