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.
