The term "skarim-porno" seems to be a combination of two words, one in English and the other possibly in a different language. I will try to break it down for you.
"Skarim" could potentially be derived from the Swedish word "skrämmis" which translates to "scare" in English. However, it is also possible that it might not have any specific meaning and could simply be a user-created term or typo.
"Porno" is simply the Finnish or Scandinavian term for pornography. It is derived from the English word "porn," meaning explicit sexual content.
Putting them together, "skarim-porno" could potentially mean "scare porn" in a mixed language context. This may refer to a type of pornographic material that features elements of fear, suspense, or horror, which is not very common but can be found in some specific fetishes or niche genres within the adult industry. Remember that this might not be an officially recognized term, and it could just be a user's way of describing their personal fantasy or experience.
