What's a good word to describe someone who makes messes [closed]
Preferably a word that is not specific to the mess being one of disorganization. Someone who spills things, for example, should be included.
I would call them a klutz:
a person who often drops things, falls down, etc. : a clumsy person
(From Merriam-Webster.)
A slob. That's not to do with disorganisation, it's more like someone who doesn't clean up around their house. Oxford Learner's Dictionary defines slob as "a person who is lazy or rude or who dresses carelessly". I'd add "generally untidy and messy in habits," and is the word I would use in your case.
