Christopher Columbus Disorder (CCD) is a mental disorder in which the afflicted believe they have discovered something new, when in fact, indigenous peoples have known about the "discovery" (i.e., object, phenomenon, area, species, etc.) for time immemorial.
Speaker 1: Hey, did you hear Dr. Pumpkinstein discovered a new mammal species in Central America?
Speaker 2: Central America, you say? Haven't there been indigenous people living there for thousands of years with traditional stories about that same mammal passed down for generations?
Speaker 1: Well ya, but if they knew about it, they never published a paper on it.

Speaker 2: Sounds like Dr. Pumpkinstein has a case of CCD.
Speaker 1: CCD?
Speaker 2: Ya, CCD... Christopher Columbus Disorder. Because Columbus didn't discover sh*t!
