So, you agree with me then. You can't say "What do you call a sleepy cat? A /grumbea-gle/ (grumpy-beagle)!" It's a portmanteau, sure, but it is not really even close to the input. Using word2vec here is probably wrong, or should have different pruning for word variance. It's a flaw of the technique and choices of the author.
