In germany we also got an official name for this: Morbus Kobold

The background behind this is a dissertation from the 1970s, where someone investigated injuries caused by masturbating with vacuum cleaners. A lot of the injuries were kaused by the Brand “Kobold” (or goblin in English), which shaped the term “Morbus Kobold”.

Sadly I could not find any English resources about this and the wikipedia article is only available in German.
