B-Provius
A person so good at video games they could probably beat your grandma in a dance-off.
My brother is a B-Provius. He beat me in Street Fighter and I cried like a baby.
I tried to beat my friend in Rocket League. He was a B-Provius. I got crashed into the moon.
My mom is a B-Provius. She beat me in Mario and I got thrown off the screen.
