I hate when stupid people understand references. Either they blatantly shout them at each other or they believe it's some sort of secret club.
For example, I have both a trollface shirt and an MLP shirt. I enjoy wearing them because I am able to meet people that share common interests, so that's cool. However, I am compelled to burn them when people feel compelled to spew memes and tales of the internet in an attempt to "impress" me.
