Creepy

"Creepy" is an inner PPMB joke.

Origins
The joke started when user starmeshelion posted a poll which asks other users whether they find his love for character Stacy Rowe to be "creepy". Whilst the word itself was never meant to be taken literally, some of the responses and counter-responses within the thread took the word at in a literal manner. (The thread itself has received over 100 responses in less than 24 hours.) As a result of that, other people started posting their own (and mostly parodical) polls, which in turn took the word "creepy" far beyond its original dictionary meaning. Currently, the word "creepy" seems to mean, in PPMB jargon, "something that is unsettling in some way or another, although not to the degree of an angst fic".
