A conjunction of "hashtag activism"; a useless, noxious form of "activism" that takes place in 144 angry, hateful characters or less. This is usually a response to taking offense to something, but ironically is often more offensive than what it is responding to.
If your tweets are angry ramblings about what you find offensive and inappropriate followed by numerous hashtags meant to blame and demean your subject, you are guilty of hagtivism.
