Charush
A guy who is smarter than Einstein, and even Joe Mama. He is better than you at everything (and there is no point in arguing). You may not know him, most likely because he is not famous...yet. But keep your valuables home cuz they tend to disappear when he is nearby, if you get what I mean.
Person 1: I aced a test!
