B-Provius - A person who plays games so well they might as well be a wiz

A person who plays games so well they might as well be a wizard with a controller.

My cousin is a B-Provius. He beat me in NBA 2K and my basketball skills died.

I tried to beat my dad in Grand Theft Auto. He was a B-Provius. He stole my car and my dignity.

My friend is a B-Provius. He beat me in Fortnite and I got eliminated before I even blinked.
