a virus that causes you to vomint and have diarrhea. It sounds like the word Ewok and whenever I hear "norwalk" I imagine the cute and loveable Ewoks chilling out on Endor playing drums and all getting sick from bad seafood.
My boss contracted the Norwalk Virus, almost shit her pants and had to go home. As a result there was no one at work to stop me from logging on to urban dictionary and defining the word "Norwalk"
