Ripperology 

Ripperology is defined as being the study of the infamous serial killer Jack the Ripper. Though the term has not made its way into the mainstream, those who study the case, or are simply enthusiasts are referred to as 'Ripperologists'.
This does not simply refer to finding out who the killer was, but who all of the victims were, along with various "evidence" such as the highly debated credibility of the Ripper letters.

"The study of the Jack the Ripper is called 'ripperology'."
"Who is Jack the Ripper, and why do I keep hearing his name? Why not ask a ripperologist?"

Reppertology 

The postmodern religion that worships and acknowledges the glory and sanctity of Michael Repper. This religion often references a phrase, "W.W.M.R.D.?", in relation to the Christian catch phrase, that reminds his followers to take initiative in their lives and to continually make Him, the deity of all, proud of them, as the earthly inferiors that they are.

"Reppertology guides me through life's trenches, like a mink stole bundled around a porcelain doll that is being tossed across the Grand Canyon."

"Reppertology is the anti dank."

"Michael Repper prophesies to the Reppertologists every morning on the Art Attack Live, where he acts as the authority on life itself."
