Deep in the depths of space and time, a floating blue box appears out of nowhere. What is in this box, you may ask? Everywhere, people are on the edge of their seat to watch what comes out. Inside is the most interesting man/alien you will ever lay eyes on. His name is "The Doctor," and we will gladly be his loyal "Whovians." However, we have habits we developed thanks to the show and the countless characters in it. Now it's time to see a few things that make Whovians stick out to the world.

1. The dreaded gas mask.

Thanks to a certain episode, we have grown terrified to gas masks. If we see one for any reason, we scream and refuse to have any contact with it. We will not shake hands with a person with a gas mask on, we will not hug them, we will keep them in our sight at all times. Most of all, we will learn where their bedroom is so we can order them to bed. Even one touch from them will doom you — It takes a while, but a gas mask will forcibly grow out of you facial skin covering your face. You will become zombie-like and spread the virus.

2. Finding a reference.

Another sign of being a Whovian is the cry of joy when you randomly find a reference to the show. It can be anywhere: a comic book, a movie, another TV show or a game app. "Doctor Who" has so many references that it will be impossible to list them all. Just know when you are hanging out with a friend and they start freaking out and showing you something, like Mia in High School Story saying, "Time wimey," it means the world to us.

3. Spoilers.

The word spoilers has hilariously taken on a whole new meaning for us. Say you are walking down the street and bump into what you think is a total stranger. You quickly befriend them and moan about your life. You might say, "I wish my girlfriend/boyfriend will marry me and have an amazing kid." Chances are by that time, the stranger will give a knowing grin and tell you, "Spoilers." Most likely you are talking to you time traveling son/daughter/granddaughter/grandson or whomever. Wouldn't that be an interesting meeting?

4. Jack and Rose.

Ask someone to tell you about Jack and Rose and you will have two possible answers. The person will either go on about the tragic love story that went on during the maiden voyage of the Titanic or you will learn about the Whovians' Jack and Rose. "Doctor Who's" Jack and Rose is so much better. Jack is a captain who thought he was a con man and Rose takes a likening to him. They dance and get a little kiss. The shipping of them goes wild. (It doesn't go anywhere, though, much to my dismay.)

So, these 4 things will tell you if you met a Whovian or not. Just be subtle about it or not when asking the person and you will be on your way of taking over the world as Whovians.
