Why do you reckon people say it? Loads of people on here say it. It's just shorthand for people who are bit flighty, style over substance, into the latest trend etc. They have always existed but under different names (don't ask me the previous names).
Also, what's up with the hatred for atheists?
It's like really "internet" to be a hipster and/or an atheist but it's even more "internet" to say hipsters don't exist and atheists are fedora wearing cunts.
You hear me? sean?
What % "internet are you? I reckon I'm only 25%.
