Twihard definition: A serious/obsessive reader of the Twilight Saga by Stephenie Meyer, one leap above Twilighters.

The difference between being a Twilighter and being a Twihard, is that Twihards have embraced a new Twiligion… er…. I mean, religion based on Twilight. They live and breath Twilight. Most Twihards are for Edward and Bella.

Therefore, those Twihards are all for true love & love at first sight. Point out one thing to a Twihard, and they can relate it to Twilight instantly. Savage and wild, they need every single thing to be perfect in the upcoming Twilight movie.
