Weird. I knew the word already (though not for long), but as a non-native English speaker (German), it also always evoked pictures of scones, or in my case croissants, for me. Maybe because it sounds like "crumbling"?

By the way, on a Mac you can just force press on any word, it gives a definition. Very useful.

I wondered if it was a reference to Oliver Cromwell who was known for his utilitarian manner.

Scones sounds tastier.

Thomas Cromwell is the historical figure "cromulent" triggers for me; the Wolf Hall trilogy is worthwhile historical fiction.
