After you've hung out around a friend (especially a geek friend) or SO for far too long, you may notice that you have your own secret language. Not the kind that twins have as children, but a language composed entirely of in-jokes that have grown out of gaming sessions, favorite movies, and embarrassing events. Using Injokese in public tends to get you strange looks, and using it when two different sets of friends are together can cause failure to communicate. Eventually, you'll find that you forget the origin of the phrases, but retain their new mutated meaning. At this point you should consider finding new friends. (Not really. Friends are too valuable to lose just because you sound like idiots whenever you have a conversation.)
