what does hashtag even mean?

[Lindsey]

Hashtags are a big thing in social media nowadays; typically seen on twitter or even instagram. On those social media sites, you can click on the highlighted hashtag and see other tweets or pictures that have been tagged with the same word. For example, if you saw on twitter that somebody put #YOLO, you could be able to click on it and see the millions of other tweets that have the same hashtag. Usually when somebody uses a hashtag and it's not on twitter, they're making fun of hashtags. That's what I do.
