What does to go viral mean?

Answer 1

The term refers to a phenomenon characterized by mass dissemination of an item on the internet or other media. It is called viral because of the similarity in which actual viruses are spread. Generally one person will show the object in question to his or her contact, who will then in turn show it to their contacts, and so on. This can refer to emails, videos, pictures or anything else that gains popularity rapidly through word of mouth.
