The word is a hybrid of the expressions "shit!" and "dayummm (as in damn)!". When used it means that the incident or anything that is being described is cringingly bad and amazing at the same time. Although the 2 words from which it originates is part of the american lingo, shiyum is popularly used in the medical colleges in south india.
