Shiesty usually refers to an action that is greedy and/or inconsiderate. When someone is shiesty it means they dont think about others and do things that help them even if they know it harms someone else in anyway.
An example of when someone is shiesty is; You ask someone for gum and they say they don't have any, but he/she really did have gum but didnt want to give you any.

Based on the word "shyster," meaning "an unethical, unscrupulous practitioner, especially of law." It comes from the German term "scheisser," which literally means "one who defecates."
John Ashcroft got real shiesty after eating at Taco Bell.
