Vitanza
An Italian American who has two distinct personalities, usually one when they are sober and one when they are wasted out of their mind. The sober half of this person is generally shy and timid, while the drunk half goes hard as a mother fuc*er at everthing they do, which can include but not limited to, hitting on girls, consuming alcohol, acting like a stupid ass mother fuc*er and, just straight up winning.
