Found a word on Urban Dictionary that could have only come into being in the last decade:
|PORNXIETY||11 up, 1 down|
The brief but intense bout of anxiety and nausea one experiences when one finds someone remarkably similar looking to one's ex/ current girlfriend and believe it is her for the briefest of seconds while viewing pornography.
It is followed by an odd, shameful sense of disappointment.
"My ex looked so much like Alyssa Milano that when I first saw Embrace of the Vampire I had a Pornxiety attack."
I wonder how long before it makes it into a paper based, legit dictionary.
Pornxiety isn't a condition I personally suffer from but I am afflicted with a related ailment: Pornstalgia.
