We have the words "incel" (involuntary celibate) and "inceldom" (involuntary celibacy.) It's considered a disease, in the sense that one suffers from it and it has similar connotations to the ones surrounding "dried fish woman."
Edit: Let's see, we have a recently introduced slang phrase from Japanese for which I provide a recently introduce slang phrase in English... y'all want "reliable sources?" Neither phrase has made it into the OED or the JEDOJD. Do you think one can do better than Urban Dictionary here? Reliable sources (huge eye roll.)
