A flirt, flirts with anything female that is human and alive. Yet at the same time not aware of the flirting. For them it's as natural as breathing. Tells a lot of jokes, not all of them funny, but some of them are great. Cares about other people despite whatever he's put through loyal like a dog on a bone. Usually into video games and making obvious statements in class just to get it out there for everyone's amusement, whether that be with him or at him. Shameless and extroverted.

2) He was being such a Giulio hitting on all the girls.
3) He pulled a Giulio on stage and had that audience dying.
