This is a relic from an old tumblr I found where the writer had a contest to determine the best code word for seeing is someone was an AB. Essentially it was a nonsense question (Specifically "Have you ever been to neverland?") that an AB could ask someone if they too were AB without giving themselves away in the process. The only problem is this tumblr wasn't popular enough for the secret code to catch on. I just thought it would have been cool if it actually caught on I can think of a few people I would ask if I could do it without the risk of being wrong and subsequently found out. Is it something you would use if you could?
