A juicer is a guy who takes steroids just to look like a superhero, but he still can’t beat his dad at chess.
My cousin is a juicer because he takes steroids and flexes all the time.
My neighbor is a juicer. He’s huge, but he can’t lift my backpack.
My dad called my uncle a juicer because he takes steroids and still loses at video games.
