Noun: a
baseless opinion stemming from lack of knowledge and research in a field, doubled down on by the one making the claim even despite overwhelming facts against it. Named after BBC journalist Bill
Hayton who makes claims such as "there was no word in the
Chinese language for 'territory' until the 19th century."
A: Man, I read this book, it claims there was no word for "territory" in the
Chinese language until the
19th century.
B: Bruh, that's such a stupid
haytonism, damn clown whoever wrote that. The Chinese word for "territory" can be found in sources from the 11th century BC.
