mad clown
A sickness where people love evil clowns more than anything, even if it makes the world worse. They act like the evil clown is their soulmate.
My cousin has mad clown disease. He thinks the evil clown is his soulmate.
That guy at the haunted house has mad clown disease. He screamed at the clown and it screamed back.
My friend got mad clown disease from a movie and now thinks the evil clown is his best friend.
