Definition of hashtag

: a word or phrase preceded by the symbol # that classifies or categorizes the accompanying text (such as a tweet) You know a thing is really a thing these days when it has its own hashtag. And there it was last week, trending on Twitter alongside #cincodemayo and #happymothersday: #umpshow, which sprang up in the wake of some shockingly bad umpiring over the first six weeks of the major league season.— Joe Sheehan It's also true that a popular hashtag can benefit important and worthy subjects, such as the recently kidnapped Nigerian schoolgirls.— Mark Leibovich also : the symbol # as used in a hashtag

Did you know?

Social media has made the hashtag a ubiquitous part of Internet culture, starting with Twitter and expanding to other sites. Originally designed for categorizing posts, the hashtag can now be a tool for a supplementary coy or witty comment (e.g., #awkward). The word tag can mean "a word or phrase used for description or identification." Hash is short for hash mark, a term for what we more commonly call a pound sign (and, less commonly, an octothorp). The hash in hash mark is probably an alteration of hatch, a term for the crisscrossing of lines (as when adding shading to a drawing).
