It's better than bleen I suppose.

Speaking of, I'd be curious about a similar experiment but one that compares how grotesque, for lack of a better word, certain words sound. The word bleen makes me uncomfortable, I think because my brain automatically goes to spleen; grue isn't my favorite either but I prefer it to bleen.

I'm curious how universal that is though. Do others have similarly aligned preferences for one word over the other, or are our feelings about them more evenly spread?

I have been eaten by many of those.

"grue" has a specific meaning in philosophy: https://en.wikipedia.org/wiki/New_riddle_of_induction
