hashtagon 

(n.) A geometric figure composed of a set of tweets on Twitter whose hashtags link such that the tweets form a geometrical figure, in any number of dimensions.

Related term: hashtagonal (adj.), having the properties of such a structure.

Here are three tweets: 1) My #dog ate an #apple. 2) The #lion growled like a #dog. 3) No #lion has ever eaten an #apple. Tweets 1 and 2 link at dog, 2 and 3 at lion, and 1 and 3 at apple. The three tweets form a hashtagonal triangle (or a triangular hashtagon). The same can be done for all geometrical figures reducible to lines and vertices with any degree of connectedness, in any number of dimensions, for flat space and probably for any uniform hyperspheroidal manifold.

hashtag activism 

The kind of activism undertaken when you "do something" about a problem by tweeting or posting links to Facebook, without any intent of ever actually doing something. Nothing more than a nonsense feelgood gesture so that one can say they "did something about" whatever trendy cause they're pretending to care about. Usually only lasts a week or two before the cause is completely forgotten (i.e. it stops being cool to forward/retweet on the subject).

I forwarded a video about some unspeakable atrocities in a country I didn't know existed until I watched the video. My hashtag activism is going to accomplish something!
