Kirbstorian 

A Kirbstorian is a person who has vast knowledge of the Kirby video game series. A true Kirbstorian has knowledge that can rival that of Masahiro Sakurai, the series creator, Shinya Kumazaki, the current series director, or even Nintendo and HAL Laboratory themselves.

"That guy knows so much about Kirby!"
"I know! He's quite the Kirbstorian if I say so myself."
