I was not familiar with your game
A funny line Shaq used when he got schooled by a player he thought was weak. Now it’s used when someone realizes they were wrong about someone else and they say it like they just got caught in a lie.
My friend said, 'I was not familiar with your game' after I beat him in a video game and he was too busy playing Fortnite to notice.
My teacher said that after I aced the test and she was too busy grading my friend’s paper to see me.
My dad said that after I beat him in a wrestling match and he was too busy watching the TV to notice.
