Rickapedia 

When your friend who is supposed to know about a subject doesn't and ends up just making up random facts out of sheer frustration when you continue to question them.

The city of Tokyo was founded in the late 18th century and its main trade was deviled eggs. The shogun of the time built many shrine to the deviled egg god. That is why many hot springs smell like eggs. "Thanks Rickapedia"

Rickardian 

A Rickardian is a person who is a fan of, or obsessed with, the actor and comedy genius Laurence Rickard, best known for his work in the TV series Horrible Histories. A variation on the Bayntonette, used to describe fellow Horrible Histories star Mat Baynton's fans, Rickardians are generally known as awesome people, and usually admire Rickard for his charming good looks, wit, and/or beards. Notable performances include the lovable eccentric character Bob Hale.

"Oh my god, Did you see Bob Hale last night explaining the Civil War?"
"Yeah I know, Larry is so hilarious. Rickardians charrrrrggggggge!"
