Italian name. Most likely from Brazil

Very happy person, Stupid and innocent...to your face. Little do you know, he is pissing on your toilette seat as we speak. it's not because he is stupid and doesn't know how to pull his foreskin back and aim right, its just that he doesn't care.

A man who has the whole world fooled except for the people that live with him.

Mostly dependent upon a maid, he lets his roommates or girlfriend clean up after him. With Arrogance as his middle name, he cocks his head back and laughs as loud as he can at his own jokes.

The dinner etiquette he possesses contradicts itself. He properly uses the silverware, but he tips his cup back so the wine dribbles out the sides and down his chin, properly wiping after-wards.

Marcello's are known for being so afraid of spiders, that they will deftly attempt to kill it (with your remote) while totally spilling their red wine on your white carpet in the process.

His careless nature leads to sloppy habits like leaving his shoes in your walk space (preferably in front of your bedroom door).
