A hipster that frequently uses Twitter.
Maddi never stops tweeting about Passion Pit and Existential philosophy, she's such a twipster.

A hipster that uses twitter, a social networking site, extremely often. A twipster will most likely "tweet" about various aspects of the hipster movement especially indie bands concerts and events going on in Williamsburg, Brooklyn (the hipster capital). A twipster may tend to make many of their "tweets" ironic.
Kat is such a twipster, she's constantly tweeting links to concerts in Williamsburg and images of American Apparel models.

Someone who gloats about how using Twitter meant they knew something n. minutes/hours before you/everyone else.
