Read up on Shibboleth [1]. Using language or phrasing, it's a way to suss out members of a certain group. One can argue that the internet memes are a type of shibboleth for internet groups. One example is The Narwhal Bacons at Midnight [2]. I'm sure YC alumni have some type of shibboleth to identify themselves in situations.
