"Dungeon crawling" is any combat-centric RPG activity set in dungeons, and has been since the days of Gygax and Arneson.
Blobbers is a term which doesn't exist, but is pushed by autistic neckbeards on the Codex for some reason. They must think they're super witty and smart.
Dungeon crawlers may not be the perfect term for it, but it isn't a meaningless garbage term like "blobbers".
Trying to force this term is not going to work. It's too stupid and too cringeworthy.
Besides, if "dungeon crawlers" is "is any combat-centric RPG activity set in dungeons", then why aren't they "hack and slashers"? That's just as descriptive.
