The misdirected rage generated by fans of a particular character when that character is killed off or replaced by someone else. Often the rage prevents them from giving a fair opinion of the new character. Originates from the BBC series Doctor Who, when fan favorite Rose Tyler was replaced with Martha Jones.
Example #1

“I hate Martha Jones so much!”

“Why?”

“Because she isn’t Rose Tyler!”

Example #2

“I hate Clara Oswin Oswald!”

“Why?”

“Because she isn’t Rory and Amy!”

“That’s the Martha Jones effect.”
