A Twi-hard is a crazed Twilight Fan Girl (A book series by Stephenie Meyer i recommend the Host also by her much better than the more Popular Twilight Saga) they Love twilight more than life itself and Will do anything and everything to meet any of he actors or the author they want to be in the series as one of the main characters, and are so crazed they even think the characters are real having cardboard cutouts of them in their rooms, posters on every inch of their wall and a compute devoted to them possibly even a website or two (Or five hindred seventy nine which is not me I am only a fangirl of good things lol)
Twi-Hard: OMFG!!! LOOK AT JACOBS ABS! OH EM GEE EDWARD IS SOOO SEXXXY SHIRTLESS! BELLA I WANT TO BE YOU!!!!!!!!!!!!!!!!!

Normal Human being: Twilight is sooo cliche'....

Twi-Hard: How Dar YOU!!!!! Best books and moveis EVER Written I love Edward/Jaco with al my heart!!!!

Normal Human being: Umm they are fictional characters...

Twi-Hard: No they are real I went to Forks Edward looked at ME!

Normal Human being: Cardboard cutout...

(by this point the Twi-Hard has gathered all her obsessed friends to beat up the human and the human is layign unconsiou on ground or in a bush/tree)

(By now the Twi-hards have run back to the first ones house and are talking about twilight, acting it out, looking it up, buying twilight merch, and of course kissign pictures (yes girls and boys we know you do all of that stuff don't try to hide it)
