Here are some possibilities for what you might be thinking of:
* Dirty: This is the most likely word if "dorty" was a misspelling.
* Dainty: This word describes something delicate and refined, often used to describe food or clothing.
* Dour: This word describes someone who is gloomy, sullen, and unfriendly.
* Dorty: This could be a regional dialect word. If you have context for where you heard it, that could be helpful in figuring out its meaning.
Please provide more context if you can, and I might be able to give you a more specific answer.
