Saadath is the definition of a highly unintelligent human being that behaves, or possibly looks like a filthy animal, typically a rat or a rabid dog. This is due to the possible error in the genes that enable him/her to behave like an animal. Examples:

- If someone lashes out and attempts to scratch/claw you
- Gets aggressive easily (over small things)
- Simply a dirty person that looks like a rat or a dog
