Those pussies that are afraid to have any fun in life
they think it makes them "cool" by abstaining from drugs, alcohol, sex outside of marriage, etc...all the fun things in life. They also tend to be vegetarian or vegan. Come on. Submit to peer pressure. Don't be afraid to have a little fun every once in a while other than just beating off all day, you pussies. I used to be a vegetarian, but I realized how much of a bitch I was being.

They are easily picked out of a crowd by the numerous "X" (meaning "hadcore")and "V" (meaning "Vegetarian" or "Vegan") symbols that they have either drawn on themselves or, in extreme cases, tattooed on their bodies. They have yet to realize that they will regret said tattoos in a few years.
