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.

Get the Haytonism mug.
Hayton loves to spend time on his own. He loves video games. He can be intelligent and moody. He believes in not putting off until tomorrow what he can put of until the day after tomorrow.
When you perfect procrastinating you've pulled a Hayton.
