Lagert
Lagertism is a deadly disease that affects the Lagerstrom family. It makes you super retarded, easy to laugh at, and gives you extra chromosomes that make you look like a downsy kid.
My cousin has Lagertism. He can't even beat me in Mario Kart.
My brother is so easy to make fun of, he's got full Lagertism.
My uncle has Lagertism and looks like a downsy kid. Poor guy.
