A Christian Hipster
A Crypster is your typical horned rimmed glasses, plaid shirt, skinny jean wearing, too cool for everyone, record listening kid, untill they ask if you want to go to church with them while enjoying a cheap beer.
n. A person, usually white middle-upper class, who attends concerts featuring music aimed at primarily younger audiences. This person can often be seen wearing a fedora, or other trendy headgear. If they appear cool, they may be loaded enough to approach for free drink. Word comes from American root: hipster.
Oh my lawd, that crypster was so fucking old at that Vampire Weekend show. At least we scored some free PBR's.
