Recently I have been thinking about different types of subcultures. To me there are two types- the inclusive and the exclusive.
All subcultures are by nature exclusive in a way, but the difference is in how they react to outsiders. Examples to illustrate-
Otaku subculture, from my experience and perspective, is very inclusive. We seek to spread the social virus of anime, manga, and Japanophilisms, perpetuating the particular series that we like by sharing it with our friends so we can talk about it and bask in its glory even more. There is nothing more gratifying than sharing a series you love and seeing the other person light up when they talk about how good it is. Like any subculture, we tend to shut people out by using our own special dialect- Japanese words or jokes pertaining to our particular subculture, but it is a shorthand and a secondary source of entertainment. There is nothing like explaining what yaoi is to your poor, unsuspecting friends...
Hipster subculture exists as a conglomeration of a thousand desperate islands attempting to push each other away but afraid of being annexed by larger subcultures, so they stick together in their odd catty way. To me, it is very entertaining but also very annoying to see such shallow people grab onto something just out of trend or claim something in trend as their own 'before it got mainstream'. Theirs is an exclusive subculture, made particularly lonely by their attempt to have absolutely nothing in common with the next person, and yet manage to wear the same uniform (skinny jeans, Converse etc) and listen to bands 'you've never heard of'. Laughable, yes, but depressing in their futility.
So be part of an inclusive subculture! Learn about something new and different! Laugh with your friends, not at jokes they aren't going to get.
