fibboleth 

A shibboleth which no one actually believes, but lots of people cite as if others believed it.

"Everything on the Internet is true" -- what a fibboleth! I've never met anyone who believed that. Have you?

Fibblechips 

When you buy a piece of furniture, fibblechips are the strange misshapen pieces in the box that don't fit on the appliance and often don't even appear on the assembly instructions

Crap! what's wrong with my couch! And what are all these other parts! Did I miss a step putting it together or are these just Fibblechips?
