Short for HashFaggot: A word used to describe an individual whom has entered into a (potentially fatal) state of being caused by the stupidity of exposure to the internet and social media. Hashfaggoty results in the victim becoming a fucktard with a mental capacity so unfathomably low that all they know how to do is spam hashtags on every website on which text is alowed ( i.e. Facebook. YouTube and even Wikipedia) regardless of its functionality or use. Hashfags tend to have absolutely no life and are usually YOLO obssesed Swaggots and or dumb rich blonde beliebers who have bought/slept their way though life. HashFaggotry can become so severe that it can interfere with a person's regular communication to the point that all text that they create must contain hashtags. Eventually the hashtags become a part of the persons regular speech patterns. In many cases the person's antics have become so annoying to the people around the HashFag that they receive an ass whoopin so hard that it kills them. The most effective and readily accessible cure to HashFaggotry is a good punch in the jaw.
