The strange and inexplicable disease that causes the carrier to grow a strange and out of place hump right in the middle of their chest, I'm deadly serious. On particularly skinny people, Chest-hump-itis gives the effect of both boobies forming into one boobie.
Danny, your Chest-hump-itis is getting out of hand, your hump nearly knocked my eye out, you better get another opinion on that one.
